Introduction The vicus The castrum |
A fortress (castrum) was built in the south part of the settlement, probably during the reign of Constantine, perhaps in the years 325-330 AD.The bell-shaped plan of the fortress can still be recognized in the old town centre, because the enclosing wall with its towers had become part of a Mediaeval wall. Later houses were built on top.

Unfortunately segments were torn down in the 20th century, including a stretch that had been preserved to a height of six meters. Today some remains can be seen in the cellars of houses. There was a gate on the west side. So far no remains have been found along the river. The wall was 3.00-4.10 m. thick.
