Unawatuna is a coastal town in Galle district of Sri Lanka. Unawatuna is a major tourist attraction in Sri Lanka and known for its beach and corals. It is a suburb of Galle, about 5 kilometres (3.1 mi) southeast to the city center and approximately 108 kilometres (67 mi) south of Colombo. Unawatuna is situated at an elevation of 5 metres (16 ft) above the sea level. Despite significant development in the last decade it is still home to the endangered and endemic purple-faced langur, an unusually shy monkey species that can only be found in Sri Lanka's forests.

A Peace Pagoda is a Buddhist stupa: a monument to inspire peace, designed to provide a focus for people of all races and creeds, and to help unite them in their search for world peace. Most, though not all, peace pagodas built since World War II have been built under the guidance of Nichidatsu Fujii (1885–1985), a Buddhist monk from Japan and founder of the Nipponzan-Myōhōji Buddhist Order. Fujii was greatly inspired by his meeting with Mahatma Gandhi in 1931 and decided to devote his life to promoting non-violence. In 1947, he began constructing Peace Pagodas as shrines to world peace. The first was inaugurated at Kumamoto in 1954.
