Heidelberg Castle is a landmark of German romanticism located in Heidelberg, Germany. Perched on a hillside, it offers panoramic views of the old downtown and the Neckar River. The castle's origins date back to the 13th century, with a mix of styles reflecting its history of constructions and destructions, including Gothic and Renaissance. Although partially in ruins, key structures such as the Ruprecht's Building, the Ottoheinrich Building with its elaborate facade, and the Friedrich Building with its famous balcony remain intact. The castle's large courtyard is framed by these impressive buildings, together with the partially destroyed towers which add to its ambiance of historic grandeur. The Heidelberg Tun, a gigantic wine barrel housed within the castle's cellar, and the beautiful castle gardens are notable attractions. The castle also hosts a pharmacy museum and offers insights into the courtly life of the prince-electors, before it was destroyed by lightning and wars.
