The Sanborn insurance maps dated 1896 (Sheet 1), 1902 (Sheet 1), 1906 (Sheet 4), and 1912 (Sheet 6) depict a one story stone jail at the corner of Fredericksburg (500 block) and Comal (800 block) streets. According to the Sanborn map it was 14′ x 16′ in size. Next to it was a one story stone building labelled as “cells.” It was gone in 1922 (Sheet 5) and in its place was a one-story brick calaboose in approximately the same location. The address of the brick structure was 148 South Fredericksburg.
