The Presidio of San Francisco is one of the oldest continuously operated military forts in the United States, a place where the fog rolls in from the Pacific carrying with it the whispers of centuries past. Today, this former army post is a national park, filled with hiking trails, historic buildings, and stunning views of the Golden Gate Bridge and San Francisco Bay. But beneath its peaceful exterior lies a darker history - one of disease, death, and military discipline that has left countless spirits wandering its grounds.
From the Spanish soldiers who first established the fort in 1776, to the American troops who trained here before shipping out to fight in distant wars, to the prisoners confined in the military stockade, the Presidio has witnessed more than its share of human suffering. Epidemics swept through the garrison repeatedly, killing soldiers and their families. Military executions were carried out on the parade grounds. Young men died in training accidents, overwhelmed by the rigors of military life. And through it all, the dead were buried in the Presidio's cemeteries - some in marked graves, others in plots long forgotten.
Visitors to the Presidio today report encounters with these spirits from across the centuries. Soldiers in uniforms from different eras have been seen marching through the fog. Voices call out in Spanish, in English, and sometimes in languages no longer spoken. The historic officers' quarters are home to ghostly figures who appear at windows, walk through locked doors, and make their presence known to anyone sensitive enough to perceive them. The Presidio is not merely haunted - it is saturated with the supernatural, a place where the boundary between the living and the dead has worn thin through centuries of military occupation.
A History Written in Military Service and Death
The Spanish Colonial Era (1776-1821)
The Presidio was founded on September 17, 1776 - just two months after the Declaration of Independence was signed on the opposite coast - by Spanish Lieutenant Jose Joaquin Moraga. It was the northernmost outpost of the Spanish Empire in the New World, a lonely garrison at the edge of civilization tasked with defending Spain's claim to Alta California.
Life at the Spanish Presidio was harsh and often deadly. The soldiers and their families lived in primitive conditions, exposed to the cold, damp climate of the San Francisco Peninsula. Disease was a constant companion - smallpox, influenza, and other illnesses swept through the garrison repeatedly, killing soldiers and civilians alike. The native Ohlone people, forced into the nearby Mission Dolores, died in even greater numbers, their immune systems unable to cope with European diseases.
The Spanish soldiers who died at the Presidio were buried in simple graves, many of which have been lost to time. Their spirits, however, are said to remain. Visitors have reported seeing figures in Spanish colonial military uniforms near the Officers' Club, which incorporates portions of the original Spanish adobe structures. These apparitions speak in Spanish and seem confused when confronted, as if unaware that centuries have passed since their deaths.
The Mexican Period (1821-1846)
When Mexico gained independence from Spain in 1821, the Presidio passed to Mexican control. The garrison declined during this period, as the new Mexican government had little interest in maintaining a remote outpost on the far edge of its territory. The soldiers who remained faced neglect, poor supplies, and the constant struggle to survive in an isolated posting.
During the Mexican period, the Presidio became increasingly dilapidated. Buildings fell into disrepair, and the garrison shrank to a handful of poorly equipped soldiers. When American forces arrived in 1846 during the Mexican-American War, they found the Presidio virtually abandoned, its walls crumbling and its once-proud garrison reduced to a shadow of its former self.
The Mexican soldiers who served and died at the Presidio during this period are among the quieter ghosts of the installation. But witnesses have reported seeing figures in the distinctive uniforms of Mexican cavalry near the Main Post, particularly during foggy evenings when visibility is poor. These spirits seem to be on patrol, carrying out duties assigned to them nearly two centuries ago.
The American Military Era (1846-1994)
The United States took control of the Presidio on March 27, 1846, and immediately began transforming it into a modern military installation. Over the next century and a half, the Presidio would serve as a crucial staging area for American military operations across the Pacific and around the world.
The Civil War and Its Aftermath: During the Civil War, the Presidio served as the headquarters of the Department of the Pacific, coordinating military operations throughout the western United States. Troops trained here before deployment, and the garrison expanded significantly. The post-war period saw the Presidio become a permanent fixture of the American military establishment.
The Indian Wars: Soldiers stationed at the Presidio participated in campaigns against Native American tribes throughout the West. Many returned from these brutal conflicts physically and psychologically scarred. Some did not return at all, while others died at the Presidio from wounds, disease, or the accumulated trauma of frontier warfare.
The Spanish-American War and Philippine Insurrection: In 1898, the Presidio became a major staging area for American forces bound for the Philippines. Thousands of soldiers passed through the post, and many of those who returned carried tropical diseases that would eventually claim their lives. The Presidio's Letterman Hospital treated countless veterans of these conflicts, and many died within its walls.
World War I: The Presidio played a crucial role in America's involvement in the Great War, training soldiers for deployment to the trenches of France. The 1918 influenza pandemic hit the Presidio with devastating force, killing soldiers and civilians alike. Mass graves were dug to accommodate the dead, and the hospital morgue overflowed with bodies.
World War II: During the Second World War, the Presidio served as the headquarters of the Western Defense Command, coordinating military operations along the entire Pacific Coast. It was here that the decision was made to intern Japanese Americans - one of the darkest chapters in American history. Soldiers departed from the Presidio for the Pacific Theater, and many never returned. Those who did often carried wounds, both physical and psychological, that would haunt them for the rest of their lives.
Korea, Vietnam, and the Cold War: The Presidio continued to serve as a major military installation throughout the Cold War era. Soldiers trained here before deployment to Korea and Vietnam, and many returned in flag-draped coffins. The post's hospitals treated the wounded, and its cemetery received the dead. By the time the Presidio was decommissioned in 1994, it had witnessed nearly 150 years of American military history - and accumulated a corresponding burden of spiritual activity.
Letterman Hospital: A Legacy of Suffering
Perhaps no single building at the Presidio accumulated more spiritual energy than Letterman General Hospital, established in 1898 and expanded repeatedly over the following decades. Named for Major Jonathan Letterman, the 'Father of Battlefield Medicine,' the hospital treated countless thousands of sick and wounded soldiers over its nearly century of operation.
The original Letterman Hospital was a wooden structure that saw service during the Spanish-American War. It was replaced in 1902 by a larger facility, which itself was expanded multiple times to meet the demands of successive conflicts. During World War I, Letterman treated victims of the influenza pandemic. During World War II, it received casualties from across the Pacific Theater. During Korea and Vietnam, it continued to serve as a major military medical center.
The suffering that occurred within Letterman's walls is difficult to comprehend. Soldiers died from bullet wounds, shrapnel injuries, tropical diseases, and psychological trauma. Amputations were performed without adequate anesthesia. Men screamed in pain, cried out for mothers and sweethearts, and breathed their last in hospital beds far from home. The medical staff did their best, but death was a constant presence in the wards.
The old Letterman Hospital complex has been repurposed as part of the Letterman Digital Arts Center, now home to Lucasfilm. But the spirits of those who died there have not departed. Security guards and employees report seeing figures in hospital gowns walking through the halls. The sounds of moaning and crying are heard in empty rooms. Equipment malfunctions in areas that were once intensive care units. The dead of Letterman Hospital remain, seeking treatment that cannot be provided and release that does not come.
The Military Stockade and Executions
The Presidio maintained a military stockade throughout the American era, where soldiers convicted of military crimes served their sentences. Conditions in the stockade were harsh, and prisoners died from disease, violence, and neglect. Some inmates were executed for crimes ranging from desertion to murder, their lives ended by firing squad on the parade grounds.
Military records document several executions at the Presidio, though the exact number remains unclear. What is known is that men died here, their lives cut short by military justice. Their spirits are said to remain near the sites of their deaths, bound to the place where they met their end. Witnesses have reported seeing figures in prisoner clothing near the former stockade location, and the sounds of gunfire have been heard when no weapons are being discharged.
One particularly persistent legend involves a soldier executed for murder during the 1890s. His ghost is said to walk the parade ground at dawn, the hour of his execution, appearing as a shadowy figure that dissolves into mist when approached. Those who have seen him report an overwhelming sense of despair and injustice, as if the ghost is still protesting his fate.
The Ghosts of the Presidio
The Presidio's 1,500 acres are home to numerous ghosts, representing every era of the installation's long history. These spirits range from barely perceptible presences to full-bodied apparitions that have startled visitors and park employees alike.
The Spanish Sentry
One of the oldest and most frequently reported ghosts at the Presidio is a Spanish colonial soldier who patrols the area near the Officers' Club. He appears dressed in the leather armor and distinctive helmet of an 18th-century Spanish soldier, carrying a musket and moving with the deliberate pace of a man on guard duty.
Witnesses report that the Spanish Sentry seems unaware of modern visitors, walking past them without acknowledgment. He has been seen emerging from the walls of buildings, walking through areas that were once open ground but are now blocked by structures built in subsequent centuries. His patrol route seems to follow the original perimeter of the Spanish fort, suggesting that he continues to guard a boundary that no longer exists.
Those who have approached the Spanish Sentry report that he dissolves into mist before they can get close, only to reappear elsewhere along his patrol route. His presence is often accompanied by a drop in temperature and the faint smell of gunpowder - the smell of the black powder weapons of his era.
The Phantom Cavalrymen
Multiple witnesses have reported seeing groups of cavalry soldiers riding through the Presidio, usually during foggy conditions or at twilight. These phantom riders appear in uniforms from different eras - some in the blue of the Union Army, others in the khaki of the Indian Wars period, and still others in World War I-era cavalry dress.
The cavalry apparitions are typically seen near the former stables and cavalry training areas. They ride in formation, their horses' hooves making no sound on the ground. Witnesses report that the riders seem to be in conversation with each other, their lips moving though no words can be heard. As observers approach, the entire formation fades from sight, leaving only the lingering impression of horses and men.
Park rangers have received numerous reports of these phantom cavalrymen over the years. Some believe they are the spirits of soldiers killed in training accidents or in combat during the Indian Wars, forever riding patrols that ended more than a century ago.
The Lady of the Officers' Quarters
The historic officers' quarters along the Main Post are reportedly haunted by the ghost of a woman in Victorian-era dress. She appears at windows, looking out at the parade ground with an expression of profound sadness. Those who have seen her describe a beautiful woman with dark hair, wearing a long dress in the style of the 1880s or 1890s.
The Lady is believed to be the wife of an army officer who died waiting for her husband to return from a campaign against the Apache in Arizona. According to legend, she received word of his death while standing at the window of their quarters, watching for his return. She collapsed and died of a broken heart within days.
Her ghost is now seen at that same window, eternally waiting for a husband who will never return. Residents of the historic quarters have reported feeling her presence in the building, particularly in the upstairs bedrooms. Some have reported waking to find a woman standing at the foot of their bed, looking at them with an expression of confusion before fading away.
The Influenza Victims
The 1918 influenza pandemic killed thousands at military installations across the country, and the Presidio was no exception. Soldiers and civilians died in overwhelming numbers, their bodies piling up faster than they could be buried. The post's medical facilities were overwhelmed, and temporary morgues had to be established to handle the dead.
The spirits of influenza victims are among the most commonly encountered at the Presidio. They appear as young men and women, pale and sickly, often coughing or struggling to breathe. They are seen near the former hospital buildings and in the areas where emergency medical facilities were established during the epidemic.
Witnesses report that these ghosts seem disoriented and frightened, as if still experiencing the final moments of their illness. Some reach out to the living, perhaps seeking help that cannot be provided. Others simply wander, looking for loved ones or trying to find their way home. The energy they emanate is one of confusion and fear - the terror of young people who died suddenly, cut down by a disease they could not understand.
The Suicide in the Woods
The Presidio's wooded areas, particularly the cypress and eucalyptus groves, are home to several persistent ghostly presences. Park rangers and visitors have reported encountering figures in military uniform who appear distressed and agitated. Some witnesses have reported seeing soldiers holding pistols or rifles, only to have the figures vanish before anything happens.
These apparitions are believed to be the ghosts of soldiers who took their own lives in the Presidio's remote areas. Suicide was a persistent problem at military installations throughout the American era, as soldiers struggled with combat trauma, isolation, and personal problems. The Presidio's wooded areas provided privacy for those seeking to end their suffering.
The energy in these locations is heavy and oppressive. Visitors report feelings of despair, worthlessness, and hopelessness that seem to come from outside themselves. Some have reported hearing gunshots when no weapons are being fired, and others have found themselves inexplicably drawn to areas where suicides are known to have occurred.
The Voices in the Fog
Perhaps the most unsettling phenomenon at the Presidio is the voices heard in the fog. When the thick Pacific fog rolls in, blanketing the post in grey mist, visitors report hearing voices speaking in multiple languages - Spanish, English, and others that cannot be identified. These voices seem to come from all directions, calling out names, issuing orders, and sometimes screaming in pain or fear.
The voices are believed to be the accumulated spiritual residue of over two centuries of military occupation. Every soldier who ever served at the Presidio left some trace of themselves behind, and when conditions are right, these traces manifest as audible phenomena. The effect is deeply unsettling - walking through the Presidio fog feels like walking through a crowd of invisible people, all going about their business unaware of the modern visitor in their midst.
Some researchers believe that the fog itself may act as a conductor for paranormal activity, providing the moisture and electrical conditions that allow spirits to manifest more easily. Whatever the explanation, the voices in the fog remain one of the Presidio's most commonly reported supernatural experiences.
The San Francisco National Cemetery
Located within the Presidio is the San Francisco National Cemetery, established in 1884 and containing the remains of over 30,000 veterans and their family members. The cemetery is the final resting place for soldiers from every American conflict from the Civil War to the present, including Medal of Honor recipients, generals, and ordinary enlisted men who served their country with honor.
The cemetery is, unsurprisingly, one of the most active paranormal locations in the Presidio. Visitors report seeing figures walking among the gravestones, sometimes in uniform and sometimes in civilian dress. Flowers placed on graves are found moved or rearranged. The sound of taps - the bugle call played at military funerals - is occasionally heard when no bugler is present.
One of the cemetery's most famous ghosts is that of Pauline Cushman, a Union spy during the Civil War who is buried there. Cushman was an actress who used her position to gather intelligence for the Union Army, and she was nearly executed by Confederate forces before being rescued. Her ghost is said to walk the cemetery at night, dressed in the theatrical costumes she wore during her espionage career.
The energy of the San Francisco National Cemetery is solemn and respectful, befitting a place where so many who served have found their final rest. But it is also undeniably haunted, a place where the boundary between life and death seems particularly thin.
