Segontium Roman Fort - Caernarfon



AD 77: Gnaeus Julius Agricola arrived to govern Britain, determined to restore Roman pride in his rebellious province. His first target was north Wales, recently lost to local tribe the Ordovices. Segontium was established following Agricola's victory. It secured Roman rule for 300 years and achieved mythical status in the story of Wales. 

Segontium was to be the largest Roman fort in north Wales. 

Its primary objective was to hold on to Anglesey; an island with mineral wealth and enough agricultural land to feed an army. It stands close to the Menai Straits at the end of the road from Roman Chester. Below it runs the River Seiont which gives the fort its name; a quayside there kept Segontium connected by sea. 

A thousand soldiers lived in barracks here. It contained all the essentials for army life. Over time a garrison town known as a vicus grew up around it supplying additional services. By the time Segontium was abandoned around AD 400, Britons were Roman citizens and faced the end of the empire together. 

Stories of Romans and Britons united in the defence of their civilisation entered mythology, identifying the Welsh as descendants of those Ancient Britons. 

The Dream of Macsen Wledig is a love story between a Roman emperor and a British princess.They marry and rule the empire together from a castle in Wales called Caer Seint, i.e. Segontium.
