Fort Pasir Panjang or Labrador Battery is located within the lush Labrador Park at the southern tip of Singapore island. It was one of the 11 coastal artillery forts built by the British in the 19th century to defend the western passageway into Keppel Harbour against piracy and foreign naval powers. During the 1942 Battle of Pasir Panjang, the fort played a supporting role but a limited one in defending the Malay Regiments against the Japanese invasion at Bukit Chandu. In 1995, the site was gazetted by the National Heritage Board as one of the 11 World War II sites in Singapore.
Labrador was named after Labrador Bay which it overlooks the deep and calm water off its shores. The Long Ya Men (龙牙门) or Dragon's Teeth Gate, two craggy granite outcrops formerly stood on each side of the entrance to the New Harbour (now Keppel Harbour) as a navigation landmark to ancient mariners. The two rock outcrops were subsequently blown up by the Straits Settlement Surveyor, John Thomson, in August 1848 to widen the entrance to the harbour.
