The archipelago includes several groups of islands. The western group, located south of the Pearl River estuary andLantau Island, was formerly known to Europeans as the Ladrones, from theSpanish for "thieves". It comprisesGreater Wanshan, Guishan, and Wai Dangling Islands and the Zhizhou, Sanmen, and Aizhou groups. The eastern group, located south ofHong Kong Island, was known as the Lema Islands. Today, they are known as theJiapeng Liedao and Dangan Liedao, respectively.

The small island is in the form of two hillocks, about 24 to 30 m (80 to 100 ft) high, and the island derives its English name from the gap between them.[6] TheGap Rock Lighthouse [zh] (蚊尾洲燈塔) on the island was built to serve as a navigation aid to vessels sailing to Hong Kong. It was built by a Hong Kong contractor[which?] and partly funded by the ImperialQing Government for both construction and maintenance costs. Besides the lighthouse it had separate European andChinese[clarify] living quarters, telegraph and storage rooms.[7] It came into operation in 1892 under Hong Kong control (island still under Chinese sovereignty) staffed by British lighthouse keeper andChinese[clarify] assistants. The lighthouse lenses and windows were damaged by typhoons in1893 and1905, the keepers eventually abandoned the site, civil war in China left it in ruins by the 1930s and 1940s. Taken over in1949[clarify] by theCommunists in Beijing, lighthouse was restored in 1986 with solar panels and fully automated.[8][9][10]A small helipad was added in by the Chinese.[when?][citation needed]
