The outside of a bai is decorated with painted story-boards called storyboards. Each panel tells a scene from Palauan history, mythology, or daily life — a visual library carved in wood. Palauan storyboard carving became internationally famous and is now one of the most recognised art forms to come from the Pacific.
Traditionally, the bai was the gathering place for the men of the village, where elders would meet to discuss community matters and pass knowledge to the younger generation. Songs, chants, and dances were also performed inside or near the bai during important occasions. The building itself was considered so important that it was carefully maintained and rebuilt when necessary.
Today, bai are preserved as cultural treasures. Visitors can see fine examples of traditional bai at the Palau National Museum and in several villages. Palauan children learn about the bai and the stories on its panels as part of understanding who they are and where they come from.
