The Archibald Henderson Law Office, built ca. 1795, is probably the oldest existing structure in Salisbury.  It is a one-story frame building with a Flemish bond brick foundation and shallow hip roof.  The main facade is three bays wide with a central entrance containing a flat-paneled door surmounted by a transom enriched with geometric tracery.  The Federal style building is located at the corner of South Church and West Bank Streets.

This property is listed individually on the National Register of Historic Places.
