This view of the 13th century Caernarfon Castle from near the Aber Swing Bridge on the south bank of Afon Seiont provides a panorama of the western defenses. Let’s start on the left and look right. The arched opening is Water Gate leading from the quay to Castle Ditch Street. Behind it is the Well Tower. In the foreground is Eagle Tower and next to it is Queen’s Tower. These are three of a dozen towers encircling Caernarfon Castle. This UNESCO World Heritage Site, spelled Caernarvon in English, is one of the most popular tourist attractions in Wales. The warm hue of the façade is courtesy of a wonderful sunset.
