Connected by several bridges to its Quebec neighbour, the city of Gatineau on the northern shores of the Ottawa River, the two cities and surrounding areas are designated the National Capital Region (NCR). Though governed by separate municipal governments, the federal lands within the region are administered by the National Capital Commission (NCC), a federal crown corporation charged with the responsibility of planning and managing the federal government's interests in the NCR.
Ottawa is situated on the south bank of the Ottawa River, and contains the mouths of the Rideau River and Rideau Canal. The oldest part of the city (including what remains of Bytown) is known as Lower Town, and occupies an area between the canal and the rivers. Across the canal to the west lies Centretown (often just called "downtown"), which is the city's financial and commercial hub. Situated between Centretown and the Ottawa River, the slight elevation of Parliament Hill is home to many of the capital's landmark government buildings, including the Peace Tower, and the legislative seat of Canada. As of June 29, 2007, the Rideau Canal, which stretches 202 km (126 mi) to Kingston, Fort Henry and four Martello towers in the Kingston area was recognized as a UNESCO World Heritage Site.
