{"id":1722,"slug":"old-idaho-penitentiary-boise-idaho","story":[{"heading":null,"paragraphs":["Idaho's first prison was commissioned in 1868 and begun with a public ceremony on July 4, 1870; the first eleven inmates arrived from the Boise County Jail in 1872 and found the walls unfinished. That was by design — for decades the prison built itself, the inmates quarrying sandstone from the ridge east of Boise and raising the cell houses they would then be locked inside.","By the time it closed on December 3, 1973, more than thirteen thousand convicts — 215 of them women — had done time inside, under thirty-six wardens, through more than five hundred recorded escape attempts. The state's own tally counts 129 deaths within the walls: ten executions, and the rest by disease, suicide, murder, and failed flight.","What the inmates built, the inmates eventually burned. But the sandstone remained, which is why the file exists: the Old Pen is one of the few prisons in the atlas where a visitor can walk from the quarry to the gallows and back without leaving the record."]},{"heading":"Ten names on the list","paragraphs":["Ten men were executed at the Old Pen, six of them hanged in the yard now planted as the Rose Garden. The last was Raymond Snowden — 'Idaho's most hated man,' per the papers — put to death at 12:05 a.m. on October 18, 1957, for the murder of Cora Dean, a Garden City woman stabbed after a night of drinking. Snowden is the only man executed inside the Gallows Room itself, and witnesses reported that the drop went badly.","The list runs backward from there: Ernest Walrath and Troy Powell, hanged together in 1951; John Jurko in 1926; Noah Arnold in 1924; Fred Seward in 1909. The scaffold still stands — a preserved piece of state machinery within sight of the rose beds."]},{"heading":"The record of conditions","paragraphs":["The institution ran the full machinery of its era: isolation cells the inmates named Siberia, the Cooler, and the Dungeon, and cells serviced by honey buckets well into the twentieth century. Its most infamous resident was Harry Orchard, who assassinated former governor Frank Steunenberg with a bomb in 1905, confessed to seventeen killings, and then — by the record — became a model prisoner.","The end came by fire, not fade. Serious riots struck on May 24, 1952, when some 250 inmates seized the Multipurpose Building; again on August 10, 1971, when two stabbings accompanied the burning of the bakery and social services building; and finally on March 7–8, 1973, when inmate Larry Trujillo refused transfer to the new facility and fires took the chapel and the dining hall — the latter designed, with grim symmetry, by an inmate in 1898. Boise had grown to the prison's walls by then, and the plumbing had been making prisoners sick for years. Three weeks after the last riot, Historical Society director Arthur Hart asked that the burned buildings be left standing. They were."]},{"heading":"What witnesses filed","paragraphs":["Reports concentrate where the record is worst: the gallows area and Cell House 5, the maximum-security block, where staff and visitors describe an oppressive presence, whispers, and touches from no visible source. The lore attaches Snowden's name to the vicinity — the last name on the hanging list, kept close to the apparatus.","Today the Old Pen is one of only four territorial prisons in the country open to the public — a museum with a botanical garden at its edge, and that juxtaposition is the file's point. Every claimed hotspot corresponds to a documented event; every legend has a room you can stand in. Most haunted prisons ask you to imagine the suffering.
