Caernarfon is home to Caernarfon Castle, one of the most prominent Welsh castles in history. Built in 1283 by Edward I when he conquered Wales, Caernarfon was designed with the architecture of Constantinople in mind, and stands today as a majestic stronghold with polygonal towers and colorful stonework. The castle is open to visitors, and the town that has grown around it is a lovely place to visit. After exploring the battlements and towers of the castle, visitors can take a pleasure flight over the region with Caernarfon Air World, get their adrenaline pumping at the Beacon Climbing Centre, or explore the wood and meet Shetland ponies, pygmy goats, and pigs at Gypsy Wood.
