On the right, the highly decorated pink sandstone facade of the Friedrichsbau (Friedrich's Wing) features ornate statues of Wittelsbach electors, exemplifying German Renaissance palace design. In the background stands the Bell Tower (Glockenturm), a medieval defensive structure that survived the castle's repeated destructive conflicts. Together, these structures reflect centuries of construction, destruction, and romantic ruin that make Heidelberg Castle a landmark of German history.
