The castle's colorful, banded stone design was a deliberate attempt to link Edward I's rule to the perceived glory and imperial history of Roman Britain.
It is part of the 'Castles and Town Walls of King Edward in Gwynedd' UNESCO World Heritage site.
The Eagle Tower, the largest of the castle's towers, originally contained luxury apartments and remains the most iconic feature of the site.
The castle's defensive design includes an exceptionally high density of arrow slits, totaling more than 100 within the external walls.
Although often called the 'Welsh Windsor,' the royal apartments were never fully finished, and Edward I rarely stayed there for long durations.
Archaeological excavations have uncovered evidence of a Roman fort, Segontium, situated on the same promontory, which predates the medieval castle.
The Investiture of the Prince of Wales has taken place here twice in the 20th century: in 1911 and 1969.
The castle's gates were designed with sophisticated defensive mechanisms, including multiple portcullises and 'murder holes' for pouring liquids on attackers.
Caernarfon Castle is a fortress commissioned by Edward I following his 1283 invasion of Wales, designed to function as both a military stronghold and a royal administrative center. Its distinctive polygonal towers and banded masonry of limestone and sandstone were intended to evoke the walls of Constantinople. The site served as the primary residence of the English sovereign in Wales and is the traditional location for the Investiture of the Prince of Wales, a title most recently conferred upon the current heir to the British throne in 1969. The castle is managed by Cadw, the Welsh historic environment service, and maintains its position as one of the most complete medieval fortified towns in Europe. It stands at the mouth of the Seiont River, overlooking the Menai Strait. The site currently houses the Royal Welch Fusiliers Regimental Museum within its towers. Unlike many contemporary fortifications, the castle was never fully completed according to the original 13th-century master plan, leaving several inner ward structures unfinished.
