The old Allegheny County Jail in downtown Pittsburgh, Pennsylvania is
part of a complex designed by H. H. Richardson. The buildings are considered among the finest examples of the Romanesque Revival style for which Richardson is well known.
The jail was built by the Norcross Brothers between 1884 and 1886, and the courthouse was finished in 1888 under the supervision of Shepley, Rutan and Coolidge. The two structures are linked across Ross Street by a "Bridge of Sighs". Additions were made 1903–1905 by Frederick J. Osterling.
