Historic downtown Denison theater building · Featured stop on Red River Tours Ghost Tour #3 · Documented paranormal investigation site in Grayson County
The Rialto Theater at 424 West Main Street occupies a position in Denison's downtown commercial strip that has seen considerable change over the past century. The building predates World War II and reflects the period of active theater construction that occurred across American downtowns in the 1920s and 1930s, when movie houses and vaudeville venues anchored local entertainment districts.
Denison's downtown along Main Street developed around the Katy Railroad depot at the east end and extended westward through several blocks of commercial architecture. The Rialto's position at 424 West Main places it in this corridor, and the building's age has made it a natural focus for local paranormal investigators who associate older structures with historical residue.
Local ghost hunters have conducted multiple sessions at the Rialto using infrared cameras and electromagnetic field (EMF) detectors. A report published by KXII television cited investigators who described the Rialto as producing some of the strongest paranormal evidence they had collected. The specific nature of that evidence was not detailed in available coverage.
Red River Tours includes the Rialto as a named stop on Ghost Tour #3, which pairs it with Barrett's — another downtown Denison location with a paranormal reputation.

The Rialto Theater's paranormal reputation in Denison rests primarily on the accounts of local ghost hunting groups who have used the building for formal investigations. KXII television reported on investigators who conducted sessions inside the theater using infrared cameras and electromagnetic field meters, and the investigators described the Rialto as producing unusually strong results.
The phrasing of their assessment — 'the best evidence ever' — reflects the enthusiasm typical of ghost hunting documentation rather than a specific verified phenomenon. The reported evidence type and content was not disclosed in the news coverage, leaving the specific nature of the investigation results undescribed in the public record.
Red River Tours includes the Rialto as a named stop on Ghost Tour #3 alongside Barrett's, suggesting the building has a consistent enough reputation to anchor a dedicated tour segment. The pairing with Barrett's places it within a broader circuit of downtown Denison locations with active paranormal traditions.
