Caernarfon Castle, Castle in Caernarfon, Gwynedd, 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.

The castle stands at the southern end of the Menai Strait, north of the River Seiont's mouth, with the walled town immediately to its north. Entry is through the King's Gate on the town side and a second gate facing the river. Surfaces inside are uneven stone with many stairs to the towers.

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.
