Delft Island fort

Delft Island Fort (also known as Neduntheevu fort and "Meekaman / Meegaaman fort"; Tamil: நெடுந்தீவுக் கோட்டை; Sinhalese: ඩෙල්ෆ් බලකොටුව) was built by the Portuguese on the island of Neduntheevu in the Palk Straight in northern Sri Lanka. Later, it was taken over by Dutch, who built a barrack nearby. The island known to the Portuguese as Ilha das Vacas, was renamed by the Dutch as Delft Island.

The fort was constructed out of limestone and coral. Though now in ruins, Ralph Henry Bassett describes the fort as a "very strongly fortified fort" in his book Romantic Ceylon: Its History, Legend, and Story.
