World-famous and the embodiment of German romanticism – the Heidelberg Castle. The castle ruin reigns majestically above the rooftops of the Altstadt. The electoral princes of the Palatinate resided there for five centuries. Today, the mysterious castle enchants the city’s guests every year. The castle gardens are famous for their geometrically structured terraces: “Hortus Palatinus”, designed by the well-known landscape architect Salomon de Caus, was considered as the eighth wonder of the world by his contemporaries. Johann Wolfgang von Goethe loved these gardens, he visited them on several occasions. A bust on the terrace commemorates the great poet and thinker.
