Segontium Romon Fort is an impressive excavated fortification located just outside Caernarfon. It was founded by Agricola in AD77, and it was garrisoned for over three hundred years. It was the longest-held Roman fort in Wales and used to hold a 'cohors milliaria,' a regiment of about 1,000 auxiliary infantry, mainly recruited from Belgium and Germany. It was linked by Roman roads to the main legionary bases at Chester and Caerleon by a series of marching camps and other forts.

These echoed imperial Roman architecture, especially the walls of Constantinople. They also recalled the Welsh myth of Macsen Wledig, who dreamed of a great fort at the mouth of a river – ‘the fairest that man ever saw’. So Caernarfon is a castle of dreams. A legend brought to life. Even after 700 years it still stirs the imagination like no other Welsh castle.

Castell Caernarfon is recognised around the world as one of the greatest buildings of the Middle Ages. This fortress-palace on the banks of the River Seiont is grouped with Edward I’s other castles at Conwy, Beaumaris and Harlech as a World Heritage Site. But for sheer scale and architectural drama Caernarfon stands alone. Here Edward and his military architect Master James of St George erected a castle, town walls and a quay all at the same time. This gigantic building project eventually took 47 years and cost a staggering £25,000. The castle was born out of bitter war with Welsh princes. So of course its immense curtain walls and daunting King’s Gate were designed to withstand assault. But the polygonal towers, eagle statues and multi-coloured masonry sent a more subtle message.

Always a pleasure to ride around this area with the castle as a back drop.
