This mag­nif­i­cent Baroque palace, sur­round­ed by immac­u­late­ly man­i­cured gar­dens, is one of Germany’s most strik­ing and largest palaces. The Prince-Bish­ops Lothar Franz and Friedrich Carl von Schön­born com­mis­sioned it as a new res­i­dence, mod­elled on the Palace of Ver­sailles. Its stair­case, the Trep­pen­haus, is topped off by the world’s largest fres­co, paint­ed by Gio­van­ni Bat­tista Tiepo­lo. Today it’s home to gov­ern­ment insti­tu­tions and a muse­um, but you can still wan­der around at least 40 of its grand­est rooms.
