Market Square Park is a public park in Downtown Houston, Texas, United States. Originally set aside by the Houston Town Company as "Congress Square," the public square was used as a marketplace and city hall, which assumed the name, "Market Square." The City of Houston constructed four different market house/city halls, the first of which opened in 1840. The fourth was constructed in 1904. Market Square is a central feature of the Main Street/Market Square Historic District, a historic district listed on the National Register of Historic Places. The square is surrounded by a combination of nineteenth-century architecture and modern residential towers, with ground leases housing a variety of restaurants and bars.
