Heidelberg Castle is one of Germany's most famous landmarks, perched 80 meters above the Old Town on the northern slope of Königstuhl hill. The oldest parts date to the 13th century, and the castle uniquely combines Gothic, Renaissance, and Baroque architecture. Partially destroyed during the Thirty Years' War and the War of Palatine Succession, its romantic ruins have inspired poets and artists for centuries. The castle houses the world's largest wine barrel and the German Pharmacy Museum, offering breathtaking views over the city and the Neckar River valley.
