This tiny structure is in Bellville and stands next to the old two-story county jail that is very similar to the one in Cameron (Milam County).  It has been modified and is currently used as storage.  The date of construction is not known but it was sometime after 1906 based on the available Sanborn maps.  It has doors at each end that floor plan also exists in some known calabooses.  There is a metal door on the wall that opens into the interior.  This could have been used as a way to pass food and other objects to prisoners without opening the main door.   The two doors suggest that there were two cells.  So far, nobody has been able to identify its original function with any degree of certainty.
