Unawatuna is a town in southern Sri Lanka. It’s known for its coral reef and its palm-lined beaches, like Unawatuna Beach. Nestled in nearby jungle, the Japanese Peace Pagoda has a stupa with ocean views. The Sea Turtle Farm and Hatchery south of town protects endangered species. North across the bay is the city of Galle’s fortified old town, founded by the Portuguese and expanded by the Dutch in the 17th century.
