Trincomalee, popularly known as Trinco, has a huge, natural harbour, however it was never developed – apart from being a base of the Sri Lanka navy today, and being guarded by Fort Frederick, which bears the date 1676 above its arch. The fort is open to visitors who can walk to the summit for a view of the harbour and of Swami Rock behind the Koneswaram temple. A city with its own unique culture, travelers to Trinco will be able to experience an entirely different world with unique cultural sites and attractions.
