佛堂門天后古廟建於南宋理宗時期，是全港天后廟中最古老、規模最大的一間，故稱大廟。獲古物諮詢委員會評定為一級歷史建築物。
西貢佛堂門天后廟曾分別於1804年（道光二十年）、1877年（光緒三年）、1962年及2009年重修。
每年農曆3月23日是天后誕，當天前來參拜的信眾絡繹不絕，達三四萬人之多。善信更喜歡到側殿摸龍床，以求子嗣、健康及財帛。今年因冠狀病毒疫情取消慶祝。
Built in the Li Chung period in the Southern Song Dynasty, the ancient temple of Tin Hau was the oldest and largest in Hong Kong. It was classified as a Grade I historical building by the Antiquities Advisory Committee.
The Tin Hau Temple at Tai Mui Wan, Sai Kung was rebuilt in the 20th year of Tao Kwong (1804), the 3rd year of Kwong Shui (1877), 1962 and 2009.
