Market Square was laid out by surveyor George Wood in 1784. The first Allegheny County Courthouse was constructed in the square along with a horseshoe-shaped market in the 1790s. In 1852 both structures were replaced with a new Pittsburgh City Hall and market, called Diamond Market. Finally, in 1914, these structures were replaced with a final market house that was razed in 1961.
Over the decades the square was remodeled and reimagined, transforming into an open-air multipurpose space in the heart of the city. Traffic through the square was eliminated in 2009 to create a more pedestrian-friendly space.
Summer in the Square is a beloved part of the Downtown Pittsburgh experience. Events sponsored by the City of Pittsburgh and Downtown Partnership fill the Square with life each year.
