Downtown Historic District
The Round Rock Historic Commercial District was added to the National Register of Historic Places in 1983. The district consists of the buildings fronting the 100 and 200 blocks of E. Main Street and the Old Post Office/Masonic Lodge at 107 S. Mays Street. Many of the buildings in the District were built in the late 1800s when the railroad was first extended to the area, stopping just short of the original town of Round Rock on the Chisholm Trail.
