Situated to the west of Tang Chung Ling Ancestral Hall, Lo Wai was the first walled village built by the Tang clan in the area. Located on a small hill, it was enclosed by brick walls on four sides. The original village entrance faced north, but was relocated later to face east in order to generate better feng shui, and it was also designed to be narrow to facilitate the defence of the village. Next to the entrance is a well, which provided the village with its water supply. The houses inside the village are arranged in an orderly manner. A raised platform was built on the north wall to serve as a watchtower. Although the village has undergone several changes, the village wall and layout of the village still exist.
The entrance tower and enclosing walls of Lo Wai were declared monuments in January 1997, and a full restoration was undertaken accordingly with the generous financial support of the Hong Kong Jockey Club Charities Trust.
To avoid any inconvenience for local residents, the interior of Lo Wai is not open to the public
