Market Square (Pittsburgh)
Market Square is a public space located in Downtown Pittsburgh at the intersection of Forbes Avenue and Market Street. The square was home to the first courthouse and first jail, and the first newspaper west of the Allegheny Mountains, the Pittsburgh Gazette. A public/private modernization in the late 2000s has re-established the square as a social and cultural hub. A great number of restaurants, ranging from fast casual to fine dining, cafes and retailers occupy ground level buildings immediately facing the square, while housing units and offices occupy upper levels.
History
George Woods and Thomas Vickroy, while creating the city block plan for streets in Pittsburgh's core, created Market Square in 1784. It was known originally as "Diamond Square" or "Diamond Market" for the Scotch-Irish idiom "Diamond" representing a public commons or square.Seat of government
By the mid-1790s, the first Allegheny County Courthouse was constructed in Market Square. It was occupied until 1836 when construction was completed on a Grant Street complex several blocks away.On December 7, 1818, the United States District Court for the Western District of Pennsylvania gaveled in its very first session at the square.
On July 8, 1794, the newly formed "borough" of Pittsburgh established a "Public Market House and Stalls" on the eastern half of the square. It also was the site of the original city hall for the borough and then city of Pittsburgh until May 22, 1872 when the second city hall opened at Oliver and Smithfield. The Courthouse was abandoned at the square in 1836 after the completion of a new county seat, and sold to private interests at auction on August 11, 1841.
