Tung Chung, meaning "eastern stream", is an area on the northwestern coast of Lantau Island, Hong Kong. One of the most recent new towns, it was formerly a rural fishing village beside Tung Chung Bay, and along the delta and lower courses of Tung Chung River and Ma Wan Chung in the north-western coast of Lantau Island. The area was once an important defence stronghold against pirates and foreign military during the Ming and the Qing dynasties.
