Our Lady of Joy Abbey, Trappist monastery in Tai Shui Hang, Lantau Island, Hong Kong.

Our Lady of Joy Abbey is a Trappist monastery built on the slope of Tai Shui Hang, made up of a church, a small garden and dormitory buildings, with a road leading down to a pier by the sea. The uphill path is laid out as a Via Crucis of fourteen Stations of the Cross. In the garden stands a Marian pavilion with a Chinese couplet and a Latin inscription meaning peace to those who enter and health to those who leave.

Trappist monks from Zhengding, Hebei, fled after thirty-three of their number were killed, moving to Xindu, Sichuan, in 1947. After the communists took Chengdu at Christmas 1949, Father Paulin Li led the survivors to British Hong Kong. The monastery was founded in 1950 at Tai Shui Hang, Lantau, on land leased from the government, and its main buildings opened on 19 February 1956.

The name Our Lady of Joy Abbey, adopted in 2000, replaced the earlier English name Trappist Haven Monastery. In the small garden stands a Marian shrine with a Chinese couplet and a Latin phrase rendered as "PAX INTRANTIBUS, SALUS EXUENTIBUS" (peace to those entering, health to those leaving). The monks follow the Rule of Saint Benedict, dividing their days between prayer, work and study, and they also bake cookies.

The monastery has no road access for cars; it sits on the hiking trail between Nim Shue Wan and Mui Wo and serves as a rest stop halfway. The only public transport is the kai-to ferry from Discovery Bay or Peng Chau, whose some sailings call at Tai Shui Hang pier, also called the abbey pier, at the foot of the hill; from there a path climbs to the buildings.

The dairy that began with one donated cow in 1953 grew into the Trappist milk brand, sold on Hong Kong Island by the 1970s before production moved to a Yuen Long factory in the 1980s. Around the abbey, feral cattle descended from the old herd still roam free.
