The city is divided into many neighbourhoods, many of which were towns that were annexed by the growing city. There are also several independent cities in and around Los Angeles, but they are popularly grouped with the city of Los Angeles, either due to being completely engulfed as enclaves by Los Angeles, or lying within its immediate vicinity. Generally, the city is divided into the following areas: Downtown L.A., East L.A., South Central, the Harbour Area, Hollywood, Wilshire, the Westside, and the San Fernando and Crescenta valleys. Some well-known communities of Los Angeles include Watts, Venice Beach, the Downtown Financial District, Los Feliz, Silver Lake, Hollywood, Hancock Park, Koreatown, and the extremely affluent areas of Bel-Air, Hollywood Hills, Pacific Palisades, and Brentwood.
