At the end of the Bockenheimer Anlage, the Eschenheim Tower (Eschenheimer Turm) shines out at us on the right-hand side. It was one of 42 watchtowers of the former city fortifications. One of many? No, the finest of its kind and quite old: built in 1428. Incidentally, also probably the highest city tower in Germany.
