Hong Kong is on China's southern coast, east of Macau, on the east side of the mouth of the Pearl River estuary. It is surrounded by the South China Sea on all sides except the north, which neighbours the Guangdong city of Shenzhen along the Sham Chun River. The territory's area (2754.97 km2 if the maritime area is included) consists of Hong Kong Island, the Kowloon Peninsula, the New Territories, Lantau Island, and over 200 other islands. Of the total area, is land and is water. The territory's highest point is Tai Mo Shan, above sea level. Urban development is concentrated on the Kowloon Peninsula, Hong Kong Island, and in new towns throughout the New Territories. Much of this is built on reclaimed land; (six per cent of the total land or about 25 per cent of developed space in the territory) is reclaimed from the sea.
