Allegheny County Courthouse

A National Historic Landmark

Alleghany County, PA

Listed in NR: 03/07/1973

Designated an NHL: 04/11/1976


When architect Henry Hobson Richardson realized his days were numbered, he wrote: “Let me have time to finish Pittsburgh and I should be content without another day.” He was referring to the massive buildings he had designed for Allegheny County in 1883, which were then being built. The jail – most rugged and solid of Richardson’s designs – was completed in 1886, and the adjoining courthouse – more specifically Romanesque in its stylistic allegiance – was completed in 1888, a year after his death. The stone group is rightly considered among the truly great examples of his individual architectural syle, the Richardsonian Romanesque.
