Mannar Fort (Tamil: மன்னார்க் கோட்டை, romanized: Maṉṉārk Kōṭṭai; Sinhala: මන්නාරම් බලකොටුවMannaram Balakotuwa) is located on Mannar Island, Sri Lanka. It was built by Portuguese in 1560 and christened São Jorge.[1][2] The fort fell to the Dutch in 1658, and they rebuilt the fort in 1696. In 1795 the British occupied the fort following the surrender by the Dutch.[3][4]
It is a square-shaped fort with four bastions and is located next to the new bridge that connects the mainland with the Mannar Island.[5]
