Dated 1820-30 this building was formerly the old prison in Ross. It consists of a small, square, red sandstone building with a hipped slate roof. At the front of the building, at the ground floor level, are 2 high pointed arched windows with iron bars. There is an identical window above the front door. Above the two ground floor windows are two very narrow openings, similar to the arrow slits found in medieval castles. The doorway also has a pointed arch and a studded grill.

The prison has since been converted into what must be one of the county's more unusual homes.

The prison is not marked on the 1880's First Edition OS Map nor the 1838 Tithe Map.
