The Celtic-Roman settlement: the area encompassing the Pfingstwiese (a large open space where various events are held, including the Jahrmarkt annual fair) and Gensinger Straße was once the site of a Celtic village and a Roman fort. In the Frankish period, this area served Frankish kings as a temporary residence (Pfalz = palace) when travelling. This is also where the town’s oldest church once stood. A piece of the old Roman fort wall is all that remains today. Now, a school complex is situated on the remnants of the past and a large industrial area adjoins the school grounds.
