Built by the Romans in AD 77 on the outskirts of Caernarfon, the Segontium Roman Fort was once the most important military base in North Wales. The Segontium was built on higher ground to better defend itself. Today, you can enjoy an interesting slice of history and views over the Menai Straits. The grounds are open from 10am - 4pm and entrance is free.

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.
