Built four to six years after the courthouse, the jail, as one would expect, was built as a substantial two story brick building with heavy bars on all the windows (which are few and small) and a single, heavy steel barred door. Under the building is a rubblestone foundation, the stones mortared in place.
We have no knowledge of exactly when the building was last used as a jail, though we have an inkling that it is presently used for storage by various departments within the courthouse.
