One of the greatest technical cultural monuments of the early Middle Ages: the Fossa Carolina (Charles' Ditch). Charlemagne had a 3,000-meter-long canal dug here in around 793 to enable ships to travel comfortably to the southeast of his empire. A 500-meter-long stretch of water and adjoining earthen ramparts bear witness to the first attempt to connect the Rhine, Main and Danube by a waterway. The square invites you to linger, with beautiful display boards, seating areas and public toilets - practically everything is there.

On the order of Charles d. Large 793 built canal between the Swabian Rezat and the Altmühl - and thus first connection between Rhine and Danube. (Later connections: Ludwigs Canal, Main-Danube Canal). The fossa carolina is said to have been originally about 3000m long; Today, only a small part of it is to be visited in mostly wooded terrain.
