Nidum

About

Nidum is a Roman fort found in Cwrt Herbert near the town of Neath, in Wales. An Auxiliary fort first built in around AD 74 from earth banks and wooden structures, it underwent a reduction in size from 3.3 hectares (8 acres) to 2.3 hectares (6 acres) soon afterwards. It may have been garrisoned by perhaps 500 auxiliary troops.

It was abandoned in around 125, but re-occupied around 140 when it was rebuilt in stone. However it was only occupied until 170, with 100 years of disuse before a final period in use from 275 to 320.
