University Hall is located in No. 144, Pokfulam Road, west of the Main Campus. The present University Hall, originally Douglas Castle, named after the Scottish business man Douglas Lapraik who built it around 1860, remains one of the University's landmark buildings.

The Mission Etranferes de Paris took over Douglas Castle in 1894 to operate the Nazareth Press for the monastery. It was acquired by the University in 1953 and named University Hall. Of neo-gothic style, the Building is best known for the elephants at its entrance, and the spiral stairs leading from the crypt to the dining room. The Hong Kong government declared it a historical building on September 15, 1995.
