Burglengenfeld
Burglengenfeld lies on the Naab north of Regensburg, beneath a castle whose name appears in a record of 1205. The future Emperor Ludwig IV lived at the castle for about two years around 1300. An iron hammer at nearby Kai was recorded in 1387 as a member of the Upper Palatinate ironworkers' association. After the Landshut War of Succession the town passed to the new duchy of Palatinate-Neuburg, and in 1542 it received town rights and a coat of arms.
