Much of the site is on the grounds of Dwr-y-Felin Comprehensive School but archaeological digs have also found gate-towers that extended out beyond the fort's walls (a feature unique in Roman Britain) and a large Roman marching camp which would have accommodated thousands of troops. These finds indicate some of the unusual measures taken by the Romans during the resistance of the native Silures and the fort at Neath was abandoned in around 125AD for fifteen years and again in around 170AD for a century before the final Roman withdrawal around 320AD.
