() is an island
off the northwest coast of Kennedy Town
on the Hong Kong Island
in Hong Kong
, separated by the Sulphur Channel
A smaller island nearby to the east, uninhabited, is called Little Green Island
Green Island is largely uninhabited and at the east coast is Green Island Reception Centre
and Green Island Police Station
. Top of the hill is an office of Marine Department
and a light house southwest guides the ships in Sulphur Channel.
The buildings of the Green Island Lighthouse Compound
were declared as monuments
in 2008. The historic buildings include the two lighthouses built in 1875 and 1905 respectively and the European quarters of the lighthouse compound. These three buildings are individually Grade II historic buildings
The island is densely covered with woodland
and tall scrub. A total of 150 plant species and a large variety of butterfly species have been found. One ant species not previously found elsewhere in Hong Kong was recorded on Green Island. The locally rare reef egret
and white-bellied sea eagle
have been seen on the island.
Administratively, the two islands are part of Central and Western District
In the 1990s, the Hong Kong Government
has proposed reclamation of Sulphur Channel and turning Green Island into a residential area, with an exit of cross-harbour tunnel of Route 10. The proposal was put off due to strong opposition from environmental concern groups.
