Caernarfon Castle, Medieval fortress in Caernarfon, Wales
Caernarfon Castle is a medieval fortress on the banks of the River Seiont in Wales, recognizable by its polygonal towers and thick stone walls. The complex comprises thirteen towers and two gatehouses connected by curtain walls that enclose a large courtyard.
The castle was built from 1283 onward under King Edward I of England to demonstrate English power in Wales following conquest. Work continued for several decades and was completed in the early 14th century, with the fortress later besieged during the Welsh uprising led by Owain Glyndŵr in the 15th century.
The fortress served as the setting for Prince Charles's investiture as Prince of Wales in 1969, when thousands of spectators gathered in the courtyard to witness the ceremony. Visitors today can explore the Eagle Tower, named after the eagle sculptures on its turrets and once home to the royal lieutenant.
Access is through two entrances on different sides of the complex, with the main entrance located near the town center. Visitors should wear sturdy footwear as many stairs and uneven stone pathways lead to the towers and ramparts.
The walls and towers of the fortress feature bands of colored stone that recall the Theodosian Walls of Constantinople, giving the structure an unusual appearance. This choice was meant to represent the connection between Welsh legend of Emperor Magnus Maximus and Roman heritage.
