Caernarfon Castle
About
Castell Caernarfon is the reason Y Maes has a castle at the bottom of it. Cadw, which runs it, says Edward I and his military architect Master James of St George built the castle, the town walls and a quay at the same time, a project that took 47 years. The polygonal towers and banded stone were meant to echo imperial Rome and the walls of Constantinople, and the Welsh tale of Macsen Wledig, who dreamed of a great fort at a river mouth. Be precise about the World Heritage status: UNESCO inscribed the Castles and Town Walls of King Edward in Gwynedd in 1986 as one property in four parts, and Caernarfon's part is the castle and its town walls together. The Royal Welch Fusiliers Museum is in two of the towers and is included in the ticket. Cadw notes the upper floors of the King's Gate and its lift are currently closed, and the terrain is graded strenuous, with uneven steps and steep, windy towers.
