Segontium Roman Fort

Segontium is a Roman fort for a roman auxiliary force, located on the outskirts of Caernarfon, Gwynedd. Founded in AD77, it was protected until AD394 and no other Roman fort in Wales has been guided for that long. The name comes from the river 'Sego' meaning vigorous and in it's modern form 'Seiont'

The first excavations were undertaken between 1921 and 1923 by R.E.M Wheeler and many of the stone buildings on view today were uncovered at this time. The original timber defences were rebuilt in stone in the first half of the 2nd century. The site is now cut through by the A4085 road to Beddgelert but most of the buildings are preserved.

Segontium is implied in the name of the surrounding town of Caernarfon because 'Caer' means fort in Welsh. The town is the corrupted form of 'Caer yn ar-fon' meaning 'Fort in (the land) opposite Mon'
