History+
The origins of the settlement date back to prehistoric times, when lead and silver were already mined here. Under Roman rule, the site developed into a city, which became part of the newly established province of Britannia Prima in the 4th century. Extensive earthworks, covering an area of about twelve hectares, indicate dense construction and intensive industrial use.
