On top stands the 'Ermita San Juan de Gaztelugatxe (in Basque: Kasteilfelsen), an old 10th-century chapel dedicated to John the Baptist, once a monastery of the Knights Templar. The sea, but also battles and fires, has destroyed the chapel more than once. Through the centuries, the church has been rebuilt and renovated several times.
