Nidum (or NIDVM) is a Roman fort found in Cwrt Herbert near the town of Neath, in Wales. An Auxiliary fort first built in around 74AD from earth banks and wooden structures, it underwent a reduction in size from 3.3 to 2.3 hectares (8 to 6 acres) soon afterwards. It may have been garrisoned by perhaps 500 Auxiliary troops.^[2] It was abandoned in around 125AD, but re-occupied around 140AD when it was rebuilt in stone. However it was only occupied until 170AD, with 100 years of disuse before a final period in use from AD 275 and 320.^[3]
