The park is built around the spring of Nemausus, which gave the town its name; it includes a ruined temple attributed to the hunting goddess Diana, and the octagonal Tour Magne, once part of the Roman walls.
The town contains ruins of Roman society such as a temple to Diana and remnants of the old city walls.
Basket weaving and willow work, another of Madeira's most important export trades, also depend upon locals working out of their own homes.
