Mannar is the main town of Mannar District, Northern Province, Sri Lanka. The town is located on Mannar Island overlooking the Gulf of Mannar and is home to the historic Ketheeswaram temple. In the Tamil language, Mannar means the raised place [of sand] which is though to have come from the geology of Mannar Island which was formed by the accumulation of sand.

History
Formerly the town was renowned as a centre of pearl fishing, mentioned in the 2nd-century CE Periplus of the Erythraean Sea.

Mannar is known for its baobab trees and for its fort, built by the Portuguese in 1560 and taken by the Dutch in 1658 and rebuilt; its ramparts and bastions are intact, though the interior is largely destroyed.
