The Old Searcy County Jail is a historic building on Center Street (Arkansas Highway 27), on the south side of the courthouse square in Marshall, Arkansas. It is a two story stone structure, built out of local sandstone, with a pyramidal roof topped by a cupola. The front facade, three bays wide, has a central bay that projects slightly, rising to a gabled top, with barred windows at each level. The main entrance is recessed in the rightmost bay.
