This simple brick courthouse has a domestic scale and presence despite being perched on a terrace above Tionesta's main street. Though the central tower has been removed, the building's surviving features are Italianate, including paired round-arched windows on the first story and segmental-arched windows on the upper, a Palladian window in the center of the front and rear elevations, and paired brackets throughout. The projecting entrance is framed by brick pilasters and has a fanlight in the center gable.
The adjacent, former jail (1895; 528 Elm Street) resembles a large Queen Anne house. Constructed of red brick, it has a hipped roof dominated by a large gable on the front and a matching dormer. Bracketed eaves line all sides of the building. Today it is the courthouse annex.
