Trincomalee is a natural deep-water harbor, on the north-east coast of Sri Lanka. On the east side of the town of Trincomalee, on a cliff known as Swami Rock stands one of the oldest Kovils (Hindu temple) in Sri Lanka. The present day Tirukonesvaram Kovil was rebuilt on the site of the Dakshana Kailayam (temple of 100 pillars) - that was destroyed by the Portugese in the 17th century. The restoration work was completed in the 1960's, and it is a "must see" site, for the visitors to Trincomalee. Friday evening Puja (offerings) services are specially colorful.
