Mountain Gatehouse (山門)
- 	Grade 1 Historic Building
- 	The main entrance to the monastery which was built in 1918 
- 	A stretch of a long wall
with a one-hall rectangular building in the middle, hanging above the recessed entrance is an eye-catching white name plaque inscribed with four characters Tsing Shan Shim Yuan (青山禪院, literally meaning green mountain meditation
cloister) painted green. Below the plaque are a pair of couplets and a pair of stone guardian lions in front of it. The gatehouse is constructed of grey brickwork with plastered finishes painted yellow. Timber purlins and load-bearing walls support its pitched roof. Two concrete benches are on the left and right of the house for visitors’ rest. Its ridge is decorated with mouldings of Sanskrit (梵文) characters and geometric patterns.
