西營盤
Sai Ying Pun is built on top of Hong Kong granite. The granite was formed in the Upper Jurassic Period and is from the last phase of intrusions in the Hong Kong area. The granite is found over most of the north and centre of Hong Kong Island, and also Kowloon. The flat parts of Sai Ying Pun near the harbour are reclaimed land, built from landfill.
