The Residence of Tang Pak Kau was probably built in the early 20th century. Tang Pak Kau (1876-1950) was a businessman and a distinguished member of the Tang clan in Kam Tin. He made remarkable contributions to the development of Kam Tin, Yuen Long and the New Territories, in particular in the areas of education and medical services. He once set up a private school inside his residence to provide education for children of the Tang clan. The residence is a rectangular-shaped single-storey grey brick building with a three-storey watchtower. The building structure and decorations of the residence demonstrate a blend of Chinese and Western styles. Most of the original building fabric, finishes and decorations are preserved in the building. The residence testifies to the development of Kam Tin, Yuen Long and Tang Pak Kau’s achievements.
The Residence of Tang Pak Kau was declared a monument in 2024.
