Since they lie between Melanesian Fiji and Polynesian Tonga, the Lau Islands are a meeting point of the two cultural spheres. Lauan villages remain very traditional, and the islands' inhabitants are renowned for their wood carving and masi paintings. Lakeba especially was a traditional meeting place between Tongans and Fijians. The south-east trade winds allowed sailors to travel from Tonga to Fiji, but much harder to return. The Lau Island culture became more Fijian rather than Polynesian beginning around 500 BC. However, Tongan influence can still be found in names, language, food, and architecture. Unlike the square-shaped ends characterizing most houses elsewhere in Fiji, Lauan houses tend to be rounded, following the Tongan practice.
