This archway once served as the divider between the Chapel and the Great Hall. In lieu of the missing floor is a catwalk so you can tour the rooms and see down to the basement. After the Conwy Castle was finished in 1287, it survived several attacks in 1295, 1399, 1401 and 1642 until it was destroyed by Parliamentary troops in 1665. Several restoration projects have occurred since the late 19th century. However, the castle is still primarily in ruins. This popular tourist attraction was declared a UNESCO World Heritage Site in 1986.
