Est. 1844 · Founded 1844 — one of Madison County's oldest Masonic lodges · Antebellum fraternal institution with Civil War-era history · Located near the Alton Military Prison Civil War POW site
The Piasa Masonic Lodge was established in Alton, Illinois, in 1844, placing its founding in the antebellum period when Alton was a significant river city and a site of considerable social and political tension around the issues that would eventually produce the Civil War. The lodge took the name Piasa, referencing the legendary creature of Illini and Algonquian tradition depicted in rock paintings on the Mississippi River bluffs near Alton.
Masonic lodges of this era were among the primary fraternal networks of the nineteenth century, drawing members across social and regional lines. The lodge's 1844 founding predates the Civil War by nearly two decades, and the conflict brought particular complexity to Masonic institutions — whose members were bound by fraternal obligations that, in theory, crossed the lines of the war.
The nearby Alton Military Prison, which held approximately 11,000 Confederate prisoners of war between 1862 and 1865, lies within the same urban area. The prison's 1,354 documented deaths — most from the 1862–1863 smallpox epidemic — included soldiers from across the Confederate states, some of whom would have been Masons. The haunting tradition at Piasa Lodge rests in part on this proximity and the bond of Masonic membership across the wartime divide.
The building's current role as an active lodge means it is not accessible to the general public, but it appears regularly in accounts of Alton's haunted history.

Apparition of a Confederate soldierFloating figure near orchestra pit areaParanormal activity in second-floor meeting room
The haunting tradition at the Piasa Masonic Lodge centers on a specific narrative: the ghost of a Confederate soldier who was a Mason and who died at the Alton Military Prison, a few blocks away, during the Civil War. The account invokes Masonic brotherhood across enemy lines — the idea that a dead Confederate Mason might return to the lodge affiliated with his order rather than to the battlefield or prison where he died.
Reported phenomena are concentrated on the building's second floor, in the main meeting room used for lodge functions. Witnesses have described paranormal activity there, including unexplained sensations and a floating figure described near what accounts call an 'orchestra pit area' within the meeting space — a spatial element present in some lodge halls used for degree work and ceremonial functions.
The accounts appear in Alton ghost-tour sources as a named location. The specificity of the Confederate-Mason identity and the second-floor location distinguish the Piasa Lodge story from vaguer building-haunting claims, though primary documentation of the specific phenomena is limited to travel and ghost-tour sources.
