Tuen Mun

Tuen Mun, also known as Castle Peak, is an area in the west of the New Territories of Hong Kong, near the mouth of the Tuen Mun River and beside Castle Peak Bay. It is one of the earliest settlements in what is now Hong Kong, with a history that reaches back to the Neolithic period. In more recent centuries the bay was a gathering place for Tanka fishermen. Today it is a modern and mainly residential district of the north-western New Territories, and around 540,000 residents lived there as of 2025. The Chinese name is written 屯門. Because Hong Kong is a special administrative region of China, the area is recorded here as part of China, with its own local character as a large residential new town.
