Caernarfon Castle

Caernarfon Castle is one of the most iconic medieval fortresses in the world and a masterpiece of military architecture built by Edward I after his conquest of Wales. Construction began in 1283 and the castle was intended not only as a fortress but also as a symbol of English royal power. Its polygonal towers and coloured masonry were inspired by the walls of Constantinople. Today the castle is closely associated with the investiture of the Prince of Wales and remains a major symbol of Welsh history and identity. Visitors can explore the Eagle Tower, medieval walls, museum displays, and panoramic views across the Menai Strait.
