Residential neighbourhoods surround the downtown in all directions; expansion is greatest to the south and west, although several areas remain underdeveloped. The city's largest park, Assiniboine Park, houses the Assiniboine Park Zoo and the Leo Mol Sculpture Garden. Other large city parks include Kildonan Park and St. Vital Park. The city's major commercial areas are Polo Park, Kildonan Crossing, South St. Vital, Garden City (West Kildonan), Pembina Strip, Kenaston Smart Centre, Osborne Village, and the Corydon strip. The main cultural and nightlife areas are the Exchange District, The Forks, Osborne Village and Corydon Village (both in Fort Rouge), Sargent and Ellice Avenues (West End) and Old St. Boniface. Osborne Village is Winnipeg's most densely populated neighbourhood and one of the most densely populated neighbourhoods in Western Canada.
