Situated west of the 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, Lo Wai 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. It was also designed to be narrow in order to facilitate the defence of the village. The houses inside the village are arranged in an orderly manner. Next to the entrance is a well, which provided the village with its water supply. Raised platforms were built on the enclosing walls to serve as watchtowers. Although the village has undergone several changes, the village walls and layout of the village still exist. A full restoration was undertaken in 1997 with the generous financial support of the Hong Kong Jockey Club Charities Trust.
The entrance tower and enclosing walls of Lo Wai were declared monuments in 1997.
To avoid disturbance to the residents, the interior is not open to the public.
