Stanley Mosque, located within Stanley Prison, was constructed between 1936 and 1937. It is the second oldest mosque in Hong Kong and the only mosque situated inside a prison compound. The mosque was initiated, funded, and built by the Indian and Pakistani Muslim staff of the Prisons Department (the predecessor of the Correctional Services Department) together with the local Indian community.
Modelled on the Badshahi Mosque in Lahore, Pakistan, Stanley Mosque represents a rare building typology in Hong Kong. It is built on a symmetrical plan along an east-west axis oriented toward the Holy Kaaba in Makkah, featuring a flat concrete roof edged by a crenellated parapet and an arcaded facade with horseshoe and ogee ornamental arches. Instead of a typical minaret, Stanley Mosque features minaret-like columns as decoration, maintaining a rich Islamic architectural character.
It retains much of its original form, with only minimal alterations made to meet daily operational needs. The mosque not only stands as a testament to the growth of the Muslim community in Hong Kong, but also demonstrates ethnic harmony within society.
Stanley Mosque was declared a monument in 2026.
Stanley Mosque is under the management of the Correctional Services Department. For security and operational reasons, it is not open to the public.
