Trincomalee & Nilaveli Travel Guide: Sri Lanka's East Coast Beaches & Koneswaram

History & Cultural Influence

Trincomalee has one of the world's great natural harbours — said to be the fifth-largest in the world — and successive empires have prized it: the Portuguese (1622), the Dutch (1639), the French and the British (1795) all fought over the port. Most visibly, the Koneswaram Temple atop Swami Rock has been a Hindu pilgrimage site for at least 2,500 years, dedicated to Lord Shiva. The Portuguese destroyed it in 1622; the Tamil community rebuilt it in 1952 and it is now one of South Asia's most spectacularly sited Hindu temples.

After decades of civil war (which ended in 2009), Trincomalee's tourism scene is firmly back. The Tamil-Sinhalese-Muslim mixed culture, the East coast's extraordinary beaches and a small but growing collection of beach resorts make Trinco an increasingly popular alternative to the south coast — especially between May and September when the south-west monsoon shuts down the country's other beach destinations.
