The town center has grown from the middle of the 2nd century on an area that encloses a former Roman manor. In the course of construction work in 1987, three cellars laid out in a row were uncovered on an area of approx. 23 m x 4.40 m, of which the southern room was restored and can now be visited. The farmhouse, which was built in 1764 and now houses Kenn's local museum, was also built on this 'Villa Urbana', which is the name of the estate.
