English: Built in 1883-1888, this Richardsonian Romanesque Revival-style building was designed by Henry Hobson Richardson and finished by Shepley, Rutan and Coolidge to serve as the Allegheny County Courthouse, replacing a previous courthouse on the same site, built in 1841 and destroyed by fire in 1882. The building features a rough-hewn stone exterior with a rusticated base, roman arched window and door openings, a stone tower on the Grant Street side of the building with corner pinnacles and a hipped stone roof, semi-circular bay windows on the Forbes Avenue and 5th Avenue facades, flanking the barrel vaulted passageways to the central courtyard, two shorter towers at the east end of the courtyard with stone roofs, which are similar in character to the main tower, gabled wall dormers, an entrance loggia on the Ross Street facade with an arched opening, an arched stone bridge over Ross Street, connecting the building with the jail on the opposite side of the street, projected corner bays with pyramidal hipped roofs, decorative carved reliefs, and decorative engaged columns. The building and the adjacent Old Allegheny County Jail were listed on the National Register of Historic Places in 1973, and were designated a National Historic Landmark in 1976. The building today remains in use for various departments of the government of Allegheny County, as well as some of the county’s court functions.
