The Friesenheimer Insel (Island) is an area in north-west Mannheim. It was artificially created by joining the rivers Rhine and Neckar with a canal during the mid-19th century. Rachel and I walked there on a very hot May day but were rewarded with a good meal and a cool beer at Debus, a restaurant on the island. We had been able to walk to the island along a thin strip of land that connected the island to the town but we returned on the Sandofen ferry which is Germany’s oldest working chain ferry built in 1897. It connects the Friesenheimer Island with Sandhofen in the northern part of Mannheim.
