History of St. Beatus Caves
The fascinating history of St. Beatus Caves intertwines geology with mythology. According to legend, the caves were the home of a fearsome dragon that terrorized the local population until it was vanquished by St. Beatus, a wandering Irish monk who arrived around the 6th century. He is said to have taken refuge in the caves before defeating the dragon, turning the site into a place of peace and spirituality. A chapel dedicated to St. Beatus stands near the site, adding deeper cultural reverence to the location.

The modern exploration and tourism of the St. Beatus Caves began in the 19th century with initial surveys revealing their immense size and geological beauty.
