Est. 1870 · 1870 limestone commercial building · Herman Dietrich Stumberg / German immigrant merchant history · Permanently sealed basement
Herman Dietrich Stumberg arrived in Texas in the mid-nineteenth century as part of the German immigrant wave that significantly shaped San Antonio's commercial and civic life in that period. By 1870 he had built a two-story limestone general store at 212 S Flores Street, a building that became one of the more recognizable commercial structures in the city's early commercial district.
Stumberg operated the store for more than a decade before his death. The building's ownership and commercial use shifted repeatedly through the late nineteenth and early twentieth centuries. At some point a basement beneath the main floor was closed off — accounts differ on whether structural concerns or a specific incident drove the decision — and the lower level has not been accessible to the public or restaurant staff since.
The Cadillac Bar & Restaurant eventually moved into the space, joining a San Antonio location of the regional Tex-Mex chain. The chain's San Antonio restaurant inherited the building's reputation along with its limestone walls.
San Antonio ghost-tour operators began documenting staff accounts from the Cadillac Bar location in the early 2000s. Local journalists at KSAT noted the Stumberg building in a 2019 list of San Antonio haunted locations, citing the sealed basement and the staff reports that had accumulated over years of restaurant operation.
Sources
The most specific and repeatedly documented account at the Cadillac Bar is attributed to a figure staff call Beatrice: a former employee whose spirit is said to remain active in the kitchen, moving or throwing utensils. Kitchen staff at the S Flores Street location have described finding utensils relocated from where they were set and, in several accounts, objects thrown without visible cause. The name Beatrice and the employee attribution appear consistently across Ghost City Tours and Alamo City Ghost Tours documentation, though no independent historical record of a specific employee by that name has been published in the sourcing available.
The second figure is described as a tall man in a white handlebar mustache, reported most often near the bar area and the location of the sealed basement stairs. Staff and tour operators have associated this figure with Herman Stumberg, citing the building's 1870 origin and his known role as its first owner. Stumberg's physical description in the accounts — the handlebar mustache in particular — is consistent with photographic conventions of German-Texan merchants of that era, though a direct documentary match has not been confirmed in the published material.
The sealed basement adds a structural dimension that operators and patrons find compelling: a space that existed in the building's original footprint, now inaccessible, with no public record of what precipitated its closure.
Notable Entities
Lunch and dinner service in the restored 1870 Stumberg limestone building on S Flores Street. The sealed basement — reportedly inaccessible since a structural incident in the mid-twentieth century — runs beneath the dining floor.
Multiple San Antonio ghost-tour operators include the Cadillac Bar as a stop on their downtown walking routes. Alamo City Ghost Tours and Ghost City Tours both cover the Stumberg building's history and the documented staff accounts.

Milwaukee, WI
Shaker's Cigar Bar occupies an 1894 Walker's Point building originally constructed as a cooperage for the Schlitz Brewing Company. During Prohibition the structure operated as a speakeasy reportedly tied to the Capone family, with a brothel on the upper floors. Bob Weiss converted it to its current cigar-bar configuration in 1986.
San Elizario, TX
The Adobe Horseshoe occupies a restored adobe structure in San Elizario, a settlement with territorial roots dating to the 16th century. San Elizario served as a county seat and witnessed the 1877 Salt War—a violent dispute over salt deposit rights that claimed several lives. The structure itself likely dates to the 19th century.
Anchorage, AK
Snow City Cafe has occupied the historic building at 1034 West 4th Avenue, on the corner of 4th and L Street, since 1998. The same building previously housed the travel agency run by Muriel Pfeil. On September 30, 1976, Pfeil was killed by a car bomb planted in her Volvo, parked in the lot directly across L Street from this building. It remains the only car bombing in Alaska's history and has never been solved.
