Castle
Wartburg
When it comes to medieval castles and their importance in German history, Eisenach's Unesco-listed Wartburg dominates the landscape. This huge medieval castle, 40,000 tonnes of sandstone on a craggy hill, has featured in a millennium of German history, and is where Martin Luther, excommunicated and under papal ban, translated the New Testament, in the process codifying the written German language. Allow at least two hours: one for the guided tour, and the remainder for the museum, Luther's rooms and the views.
