The Ancestral Hall is a Grade 2 building.
The Historic Building Appraisal on the AMO website states as follows:
"The Man clan is one of the 'Five Big Clans' of the early major settlers in the New Territories. Although not the first, the clan arrived as early as the 15th century in San Tin and in Tai Hang. There are several ancestral halls in San Tin, one of which belongs to the whole clan and others to different branches. The Man Lun-Fung Ancestral Hall, occupying the low lying ground of San Tin facing the abandoned fields of the clan, was built more than 200 years ago in honour of one of the clan's ancestors, Man Lun-fung.
