Overview
Fort Frederick guards the rocky headland that separates Trincomalee's town from its great natural harbour. It is still a working military base, but visitors can pass through on the way to the Koneswaram temple on Swami Rock, and the walk or drive is one of the most interesting in town.
History
The Portuguese built the first fort here in the 1620s, partly with stone from the ancient Koneswaram temple, which they destroyed. The Dutch took it in 1639, rebuilt it and named it Fort Frederick. Over the following century control changed hands between the Dutch, French and British, and the British held it from the 1790s. Arthur Wellesley, later the Duke of Wellington, is said to have stayed here as a young officer; the house linked to him is known as Wellesley Lodge.
What you see
- The main gateway, with its old stone walls.
- Colonial buildings and old cannons inside the grounds.
- Spotted deer wandering freely under the trees.
- The road up to Koneswaram Temple and the cliff at Swami Rock, with views over the sea and harbour.
The fort is now used by the Sri Lanka Army, so many buildings are off limits.
How long it takes
About an hour, including Koneswaram.
When to go
Late afternoon is cooler and the light is good at Swami Rock. The east coast is driest from about May to September.
Getting there
The gate is at the northern edge of Trincomalee town, a short tuk-tuk ride from the centre. You can drive in or walk up.
Practical tips
- Do not photograph soldiers or military buildings; follow any instructions.
- Dress modestly if continuing to the temple.
- Do not feed the deer or monkeys.
