佛堂門天后古廟建廟700餘年，是廣東沿岸現存歷史最悠久的天后廟之一；其規模為全港之冠，故稱「大廟」。廟內大殿供奉天后娘娘，偏殿有一口銅鐘和一張龍床。每年農曆三月廿三日天后寶誕，前來參拜的信眾絡繹不絕。Established more than 700 years ago, the Tin Hau Temple at Fat Tong Mun is the oldest among all existing Tin Hau Temples in the coastal areas of Guangdong. Being the largest Tin Hau temple in Hong Kong, it is known as “Tai Miu“ which means the “Grand Temple“. The main hall is dedicated to Tin Hau, the Goddess of the Sea, while in the side hall on the right, there are a bronze bell and a Tin Hau’s bed. During the Tin Hau Festival which falls on the 23rd day of the third month of the lunar calendar, thousands of worshippers visit the Temple to pay tribute to the Goddess.
