A mid-Neolithic prehistoric site dating back to about 6,000 years ago has been identified on Centre Island during a survey conducted in 1997–1998. Prehistoric sites have been discovered on two other islands of Tolo Harbour, namely Yuen Chau Tsai (3,000 years, Bronze Age) and Yim Tin Tsai (4,000 years, late Neolithic).
