King Law Ka Shuk is the ancestral hall of the Tang clan in Tai Po Tau Tsuen. It was once used as a study hall, and still serves as a venue for clan members to hold meetings and traditional functions. It is believed that the building was built by the 13th generation ancestors Tang Yuen-wan, Tang Mui-kai and Tang Nim-fung in the Ming dynasty (1368-1644) to commemorate their 10th generation ancestor Tang King-law.
King Law Ka Shuk is a traditional three-hall, two-courtyard building. The roof ridges are decorated with geometric motifs. The murals above the main entrance and the exquisitely carved timber altar in the middle hall were built during renovations in 1932.
The full restoration of King Law Ka Shuk was completed in January 2001 under the supervision of the Antiquities and Monuments Office and the Architectural Services Department. The King Law Ka Shuk restoration project won the Award of Merit of the UNESCO Asia-Pacific Heritage Awards for Culture Heritage Conservation in 2001.
King Law Ka Shuk was declared a monument in 1998.
