Castrum Segontium

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.

The objects found here reveal how Roman soldiers lived and worked, through coins, pottery fragments, and military equipment from different periods. These items show what daily life was like in this distant outpost of the empire.

The site is open and accessible to visitors on foot, with informational panels explaining the layout of the fort. You can walk across the ruins and explore the remains of walls and foundations at your own pace.

Excavations uncovered a rare bronze head of a Roman emperor, showing that rulers were venerated at this location. The discovery suggests the fort was more than just a military stronghold – it also held religious and administrative importance.
