Downtown Houston Historic District · Market Square Park
US Ghost Adventures is a multi-city ghost-tour operator; in Houston it runs its program under the brand Houston Ghosts. The Houston Hollow Heart Hauntings Ghost Tour meets nightly at 8pm by the clock tower in Market Square Park, 301 Milam St, and covers about a mile of downtown Houston on foot over roughly an hour.
The operator's route material centers on Houston's historic commercial core near Market Square, including buildings dating to the 19th and early 20th centuries that have since become hotels, bars, and restaurants. Houston was founded in 1837 and grew as a shipping and later oil and space-industry hub; the operator's marketing frames several of its downtown buildings' documented histories of financial hardship, workplace accidents, and 19th-century epidemics as backdrop for the reported hauntings covered on the tour.

The tour's centerpiece stop is Hotel Icon, formerly the Union National Bank building, where the operator's narrative describes Great Depression-era employee suicides amid declining business, with guests today reportedly hearing thumping noises and gunshot-like sounds. At La Carafe, described by the operator as the oldest commercial building in downtown Houston, staff have reportedly seen bottles and glasses disturbed and heard a child playing upstairs, along with sightings of a deceased former manager in an upstairs window.
The Spaghetti Warehouse is presented by the operator as one of the most haunted restaurants in America, tied to the story of a young employee who fell to his death down an open elevator shaft and his wife, who reportedly died soon after of grief; their spirits are said to disturb dishes and rearrange furniture. The route narrative also references a bar associated with Sam Houston and paranormal activity at Craft Beer Cellar.
All of this is the tour operator's own marketing and narrative material, not documented history verified independently for this listing; it is included here as a description of what the tour covers, not as an endorsement of any specific claim.
