As commerce moved north and west during the mid-19th century, the city's first seaport was transformed into a food supply center (the Fulton Fish Market opened in 1835). From the late 19th century through the mid 20th century, the area was largely abandoned, surviving only as a wholesale fish district and yachting dock. In the 1960s interest in the seaport was revived as the building industry returned to lower Manhattan. After a twenty-year debate over the future of the area, Thompson and Rouse & Company redeveloped the seaport according to a formula used at Boston's Quincy Market and Baltimore's Harbor Place. Today a tourist attraction filled with middle and high-end retail and restaurants, South Street Seaport exemplifies one way in which New York has addressed the preservation of historic architectural and urban spaces.
