A central act in the Wiyot people's spirituality is an annual World Renewal Ceremony held at Tuluwat village. Indian Island, formerly called Duluwat Island, was and is the center of the Wiyot world. On the island, at the start of each year, a ceremonial dance called the World Renewal ceremony was held, which lasted seven to ten days. Ceremonial masks were worn during the dance. All people were welcomed; no one was turned away. It was held at the village site of Tuluwat on the northern part of the island. Traditionally the men would leave the island and return the next day with the day's supplies. The elders, women and children were left to rest on the island along with a few men.
