The San Jacinto County Jail, built across Loyd Avenue from the original courthouse square in 1887 is a two story yellow pink brick building of Victorian influence. The square (28' X 28') structure with socalled 'common' brickwork is punctuated by several horizontal projecting courses and with masonry in high relief at the corners suggesting square partial columns. The building presented a handsome and solid symbol of law and order in a no-frills (and virtually fireproof) public building. The Old Jail Museum houses artifacts pertaining to the history of the East Texas and San Jacinto County are. The Old Jail Museum boasts both Texas Historical Commission and National Register recognition.
