Est. 1926 · NRHP-listed (1980) · Largest Masonic Temple in the world · George D. Mason neo-Gothic Architecture · Major Detroit Theater/Concert Venue
Detroit's Masonic fraternity began planning a new central temple in the late 1910s, eventually selecting a 4.6-acre site at the intersection of Temple Street and Cass Avenue. Architect George D. Mason — already responsible for major Detroit buildings including the Detroit Yacht Club and the Pontchartrain Hotel — drew the building in a vast neo-Gothic idiom, combining Tudor, Romanesque, and Gothic-revival motifs. Construction began in 1920; the cornerstone was laid in 1922 with full Masonic ceremony, and the completed building was dedicated on Thanksgiving Day, November 25, 1926.
The finished structure encompasses 1,037 rooms across 14 stories above grade and several below, with a footprint of roughly 550,000 square feet. The complex contains a 4,400-seat theater (then among the largest in the United States), a 1,580-seat secondary auditorium, three ballrooms, eight lodge rooms with different ritual themes (Greek Doric, Egyptian, Italian Renaissance, Tudor, Romanesque, Byzantine, etc.), hidden ritual staircases, and a chapel. The labyrinthine plan — corridors that dead-end, ritual passages closed to non-members, and decades of partial renovations — has contributed to its haunted-building reputation.
An enduring urban legend holds that Mason bankrupted himself on the project, was abandoned by his wife, and leaped to his death from the temple's roof. The Detroit Historical Society has explicitly debunked this story: Mason died on June 3, 1948, at age 91, of natural causes at his home in the Wilshire Apartment building on Grand Boulevard. He was buried at Evergreen Cemetery in Detroit.
The Temple was added to the National Register of Historic Places in 1980. It remains in active use as a Masonic facility for the Detroit lodges and as one of the city's most important concert and theatrical venues, drawing touring acts, Broadway productions, and major civic events.
Sources
Per the Detroit Historical Society, the most-told ghost story attached to the Masonic Temple is also its most thoroughly debunked. Popular retellings claim that architect George D. Mason exhausted his fortune building the temple, was left by his wife, and leaped to his death from the roof of the 210-foot tower. The Historical Society explicitly rejects this: 'While the story makes for great Halloween horror tale, it is not true.' Mason did not go bankrupt and never jumped from the roof. He died on June 3, 1948, age 91, of natural causes at his home in the Wilshire Apartment building on Grand Boulevard, and was buried at Evergreen Cemetery.
Despite the correction, the Mason-on-the-stairs apparition persists in temple lore. Guards, docents, and event attendees describe a figure ascending the stairs toward the roof, only to vanish near the top. Visit Detroit and other tourism outlets continue to feature the building as one of the city's most haunted addresses, and the Temple itself has not aggressively pushed back on the lore in its own marketing.
Other reported phenomena, repeated across multiple secondary sources, include: doors slamming on their own in unoccupied corridors; items going missing only to reappear elsewhere; windows that close themselves; cold spots felt by docents and security; and unexplained sounds — voices, distant music — in the labyrinthine 1,037-room plan after hours. The temple's sheer size and decades of partial use create natural conditions for unfamiliar noises, and the Detroit Historical Society notes that the building's secretive Masonic associations and imposing scale likely contribute to recurring haunted narratives, particularly around Halloween.
Readers should treat the Mason-suicide attribution as cleanly false. The other phenomena — apparitions, sounds, object movement — are reported broadly but anecdotally, with no named primary investigators on record.

Yuma, AZ
Yuma Territorial Prison operated from 1876 to 1909 on a bluff overlooking the Colorado River in Yuma, Arizona. It held 3,069 prisoners during its 33-year operation, including 29 women. The facility became a state historic park and has been voted by USA Today readers as the Best Haunted Destination in the nation.
Salem, MA
The Jonathan Corwin House at 310 Essex Street is the only surviving structure in Salem with direct ties to the 1692 Salem witch trials. Built circa 1675 and purchased by Corwin that same year, the house served as the site of pretrial examinations for several of the accused. The property has operated as a museum since 1948 under City of Salem ownership.
