The Round House is one of the remaining stone structures at the ghost town of Two Guns, Arizona, once a lively stop along historic Route 66. Built in the mid-20th century, likely as a residence or utility building, the circular stone design reflects the rustic charm of roadside architecture from that era. It stood near tourist attractions like a zoo and the infamous Apache Death Cave, all part of a roadside complex that peaked in the 1920s–60s before being abandoned in the following decades. 

Its design reflects the practical, hand-built architecture typical of mid-20th century roadside stops, constructed with local stone and likely serving as a caretaker’s residence or utility building, rather than a showpiece.
