Castrum Segontium, Roman archaeological site in Caernarfon, Wales
Castrum Segontium is an ancient Roman fort near Caernarfon in Wales, with remains of stone walls, building foundations, and defensive structures spread across a hilltop. The site served as a strategic military post that controlled the region and protected important trade routes.
The fort was founded in 78 AD and remained an important Roman military base in northwest Wales for about two centuries. The garrison changed over time, and the buildings were modified several times until the Romans departed from the region.
