Caernarfon Castle, Medieval fortress in Caernarfon, Wales
The castle features multiple polygonal towers connected by thick stone walls rising 9.6 meters high along the River Seiont waterfront.
Construction began in 1283 under Edward I of England, with architects James of Saint George and Walter de Hereford leading the 47-year building process.
The castle design incorporates elements from Constantinople architecture and Welsh mythology, including the legend of Macsen Wledig's vision of a fortress.
The castle maintains regular opening hours throughout the year, with guided tours available in multiple languages and dedicated parking facilities nearby.
The fortress required 25,000 pounds to complete, equivalent to several million pounds today, making it one of the most expensive constructions of medieval Britain.
