Sanatorio Durán — The Sanatorium in the Clouds
The ruined tuberculosis sanatorium built 1915-1918 on Dr. Carlos Durán Cartín's initiative above Cartago — evacuated when Irazú erupted in 1963, later orphanage and juvenile prison, abandoned since — is Costa Rica's most famous haunt: the nun who walks the wards and the little girl in the corridors, in a building whose most chilling fact is that the sanatorium's own children mostly died of the disease it could not cure.
Case File No. 487
FILE 01 The Legend
Costa Rica's tuberculosis crisis found its answer on a cold ridge near Irazú: the Sanatorio Dr. Carlos Durán Cartín, conceived in 1915 by the physician and ex-president whose name it carries and opened in 1918 to isolate and treat several hundred patients in the mountain air that was, before antibiotics, the only therapy. The disease did not discriminate and neither did the sanatorium: wards of the dying, a chapel, and children with bone and lung tuberculosis in the same corridors as adults — the demographic seed of everything told there now. Volcano and time emptied it: the 1963 eruption of Irazú, smoking on the horizon above the ridge, forced an evacuation; the buildings passed through use as an orphanage and then a juvenile detention center in the 1970s, and were finally abandoned to the cloud forest, becoming the country's premier ruin — protected as national heritage by decree in 2014. The ghosts are two, and constant across every retelling: a nun — the Sisters who truly nursed the wards, remembered in habit, walking the long galleries and the chapel — and a little girl, who appears in the corridors and stairwells, sometimes holding a ball, most often near the children's ward. The popular tellings sharpen the girl's story into tragedy: that she was Durán's own daughter, carried up to the mountain to be near her father's work, and died there. The records say otherwise, and the correction has become part of the legend's honest telling: Durán's daughter survived the sanatorium era — the mountain's dead were the poor and the tubercular, not the founder's child. Night tourism is now the ruin's second life: Sanatorio Durán is routinely ranked the most haunted place in Costa Rica and among the most haunted in Latin America, with La Nación — the national paper of record — among the outlets chronicling both its history and its ghost fame, and television documentaries walking its empty wards with flashlights.
FILE 02 The Sightings Log
The documented spine: founding 1915, opening 1918, for roughly 300 TB patients (UCR Museum of the Image's historical record); the 1963 Irazú eruption evacuation; the orphanage and juvenile-prison era of the 1970s; heritage decree 38657-C of 2014; the two-ghost canon (nun and child) in national media including La Nación; TV/YouTube documentaries and a decade of visitor ghost reports.
FILE 03 The Skeptic’s File
The nun and the girl are textbook ruin-folklore: a former hospital with a real nursing order and real children's wards will produce a nurse-ghost and a child-ghost with near mathematical certainty, and no report at Durán carries a name, a date or a record — the ball-holding girl is a motif, not a person. The Durán's-daughter story is demonstrably false in its popular form, which the honest tellings now flag — a rare case where the legend's own correction is documented. What is undeniably real is the building's history of death by disease; everything paranormal on top of it is atmosphere, guides, and the fog that rolls through the wards at dusk.
