Nördlingen Gate (around 1400): stepped gable decorated with shell shapes dating from the 16th century. Tar holes in the vaults. Town mill built after Emperor Karl IV had granted Dinkelsbühl a privilege to run two mills (1378). The municipal mill (14th century) that is built like a fortification, with a moat, a parapet and crenels, is reminiscent of a moated castle. Now houses the Third Dimension Museum, showing how Man has been trying since medieval times to reconstruct space in perspective. Cabbage beds in front of Nördlingen Gate (twenty plots), let since the middle of the 19th century to equal numbers of Catholic Protestant citizens.
