Tuen Mun is situated in the western part of Hong Kong, on the eastern side of the Pearl River estuary. Within the district, famous mountains and ancient temples abound. The area has been a place for agriculture, fishery, commerce and industry, and its villages and towns have a long history. It had long been a traffic hub for local and overseas merchants and travelers. According to the Tang dynasty historical documentation, Tuen Mun was also a place of military garrisons and commanded a key position for coastal defense.
Local and overseas scholars had carried out archaeological investigations as early as the 20s and 30s of the last century. A number of prehistoric sites were discovered in So Kwun Wat, Lung Kwu Chau and Castle Peak Bay. The Hong Kong Archaeological Society later conducted numerous surveys and sub-surface investigations. Following the enforcement of the Antiquities and Monuments Ordinance in 1976, the Antiquities and Monuments Office (AMO) commissioned two territory-wide archaeological surveys which both resulted in the discovery of various areas with archaeological potential in Tuen Mun. In recent years, the AMO has conducted further investigations and rescue excavations in response to the infrastructural works. These efforts yielded many cultural remains of Neolithic period, Bronze Age as well as Han, Tang, Song, Ming and Qing dynasties.
