Well of Sta. Lucia
This spring-fed well where two women saw the reflection of the Virgin of Caysasay, is now known as the Miraculous Well of Sta. Lucia. Since its discovery, many have attested that the spring water has miraculous healing and therapeutic powers. The spot where the well which reflected the image of Our Lady is marked by a coral stone arch with a bas relief image of the Virgin on its façade. It was built in early 1600.
This carving technique is quite ancient, and it has been used independently in many civilizations like the Angkor Wat in Cambodia, built in the 12th century and Borobudur in Indonesia, built in the 9th century.
