Cathedral of St. Declan and Round Tower
There's a story behind every ruin you pass in Ireland; behind many, there's a truly ancient story. Inside the ruined 12th-century Cathedral of St. Declan are some pillar stones decorated with ogham script (an ancient Irish alphabet) as well as weathered but stunningly abstract biblical scenes carved on its west gable. St. Declan is reputed to have disembarked here in the 5th century—30 years before St. Patrick arrived in Ireland—and founded a monastery. The saint is said to be buried in St. Declan's Oratory, a small early Christian church that has been partially reconstructed.
On the grounds of the ruined cathedral is the 97-foot-high Round Tower, which is in exceptionally good condition. Round Towers were built by the early Christian monks as watchtowers and belfries, but came to be used as places of refuge for the monks and their valuables during Viking raids. This is the reason the doorway is 15 feet above ground level—once inside, the monks could pull the ladder into the tower with them.
