Today's residents of Hong Kong live in modern high-rises - even in the less urbanised regions of the New Territories.
In the past, however, New Territories residents usually lived in walled villages. Families with the same ancestors and the same surname often lived together in the same village.
The Sam Tung Uk Village in Tsuen Wan is one of Hong Kong's rare examples of a surviving historic walled village.
With its rows of houses along two sides and the rear, the symmetrical layout of the village resembles a chessboard.
The village's history can be traced to more than 200 years ago.
In the 18th Century, members of a Chan clan moved from Longchuan county of Guangdong Province to Hong Kong and settled in Lo Uk Cheung of Tsin Wan (present-day Tsuen Wan). The Chans constructed seawalls and reclaimed land along the shore in order to plant their crops.
