The Grand Staircase and Gallery is located on the first floor of the Allegheny County Courthouse, a National Historic Landmark and masterpiece of architect Henry Hobson Richardson. Construction began in 1884 and was completed in 1888.
Its architecture is considered among the finest examples of Romanesque Revival and includes Syrian arches, Byzantine capitals, late French Gothic dormer windows, and French Renaissance roofs. One of its most striking attributes is the bell tower, which rises more than 229 feet above Grant Street. The Grand Staircase and Gallery features soaring arches and dignified columns, as well as five murals by artist Vincent Nesbert and flags of the states.
At the center of the Allegheny County Courthouse is the beautiful Courtyard, which features a central fountain and four landscaped gardens. The building rises dramatically around the Courtyard, giving guests spectacular views of its granite bell tower and turrets, arched windows, and steep slate roofs.
