The most important festival of El Hierro is the Bajada de la Virgen de los Reyes, held every four years, on the first Saturday of July (the last occasion was in 2017, and the next will be in 2021). During the festival, the Virgin of the Kings (Virgen de los Reyes, patron saint of the island of El Hierro) is taken from her sanctuary in La Dehesa (in the municipality of La Frontera) and carried to the capital of the island, Valverde, making a tour of 44 kilometres and running through all the towns of El Hierro. The annual festival of the Virgin is celebrated every September 24.
