Fort Frederick occupies the rocky headland of Swami Rock on the edge of Trincomalee town. Built by the Portuguese in the 1620s and later held by the Dutch and the British, it is still an army garrison today, but visitors can walk or drive through its gateway to the famous Koneswaram Temple at the tip of the headland.
Entry is free. Expect old walls and a stone gateway, shady roads with free-roaming spotted deer, and wide views over the ocean and Trincomalee’s natural harbour.

History of Fort Frederick
The Portuguese built the first fort here in 1623–1624, calling it the Fort of Triquillimale, using stones from the Koneswaram Temple they had destroyed in 1622. The Dutch captured it in 1639 and rebuilt it in 1665, and it was renamed Fort Frederick. During the 18th century Trincomalee’s deep harbour made the fort a prize in European wars, and the French held the town briefly in 1782.
The British took the fort in 1795 and kept it until independence in 1948. Arthur Wellesley, the future Duke of Wellington, stayed here; his former residence, Wellesley Lodge, is now an officers’ mess. Today the fort is an archaeological protected monument and is garrisoned by the Sri Lanka Army’s Gajaba Regiment.
