Batticaloa is a city in the Eastern province of Sri Lanka. It is the seat of the Eastern University of Sri Lanka. It is on the east coast, 69 miles south by south east of Trincomalee, and is situated on an island.Historic Batticaloa, Batti for short, enjoys a spectacular position surrounded by lagoons with palm-filtered sunlight glancing off the water. There’s a mellow vibe to the town, and though there are no dramatic or must-see sights, a morning exploring the compact centre and its huge fortress and many churches is time well spent. It’s not a large place and ideal to explore on foot. Sandy beaches are close by, but these were hit hard by the 2004 tsunami.
