Est. 1866 · Built by Captain Krammer (1866) as Residential Duplex · St. Charles Historic Main Street Commercial Property · Nearly 50-Year History as Main Street Restaurant
The building at 500 S. Main was constructed in 1866 by a Captain Krammer — the title suggests a river trade or military background, common in St. Charles's commercial class of the period. The duplex design was a deliberate solution to what contemporaries recognized as a universal domestic problem: Krammer wanted his mother-in-law close enough to assist the household but separate enough that the two families maintained their own spaces. The building was divided accordingly.
After the Krammer family's tenure, the property passed through various hands before being converted to commercial use. For nearly fifty years it operated as a restaurant on St. Charles Main Street, a stretch that saw significant foot traffic from tourists and locals drawn to the historic district. The building eventually became The Main House, which continued the dining tradition.
The physical structure retains characteristics of its 1866 construction — the division of the original duplex is still legible in the floor plan, and the building's age gives it the creaks, drafts, and settling sounds that contribute to its haunted reputation.

Objects moved overnight without explanationDisembodied footsteps in empty roomsGuest names appearing on Easter eggs with no staff involvementDisembodied voicesCold spots
The haunting accounts at The Main House have accumulated gradually over the property's long restaurant history rather than being tied to a single dramatic event. Staff have noted objects moved overnight — items left in one position at closing found somewhere else in the morning — with enough consistency that it became a running topic among employees.
Two accounts stand out in the documentation. First, during Easter service, the names of guests reportedly appeared written on Easter eggs without any staff member having written them — an incident that was noticed publicly enough to become part of the building's lore. Second, disembodied voices have been heard in rooms confirmed to be empty, a report that crosses multiple witnesses over time.
Footsteps moving through unoccupied parts of the building are the most common passive report. Cold spots appear without obvious drafts. The building's Krammer-era duplex origin is sometimes cited as the source — either the captain or his mother-in-law is offered as the likely presence, though neither specific death nor documented trauma is tied to the address in surviving records.
