Macau
Geography

Macau is located on China's southern coast, 60 km (37 mi) west of Hong Kong, on the western side of the Pearl River estuary. It is surrounded by the South China Sea in the east and south, and neighbours the Guangdong city of Zhuhai to the west and north. The territory consists of Macau Peninsula, Taipa, and Coloane. A 1 km (0.39 sq mi) parcel of land in neighbouring Hengqin island that hosts the University of Macau also falls under the regional government's jurisdiction. The territory's highest point is Coloane Alto, 170.6 m (560 ft) above sea level.

Urban development is concentrated on peninsular Macau, where most of the population lives. The peninsula was originally a separate island with hilly terrain, which gradually became a tombolo as a connecting sandbar formed over time. Both natural sedimentation and land reclamation expanded the area enough to support urban growth. Macau has tripled its land area in the last century, increasing from 10.28 km (3.97 sq mi) in the late 19th century to 32.9 km (12.7 sq mi) in 2018.

Cotai, the area of reclaimed land connecting Taipa and Coloane, contains many of the newer casinos and resorts established after 1999. The region's jurisdiction over the surrounding sea was greatly expanded in 2015, when it was granted an additional 85 km (33 sq mi) of maritime territory by the State Council. Further reclamation is currently underway to develop parts of the Macau New Urban Zone. The territory also has control over part of an artificial island to maintain a border checkpoint for the Hong Kong–Zhuhai–Macau Bridge.
