The castle of Heidelberg, Germany is well known to the world – because of its beauty and because of the big amount of US soldiers stationed in nearby Ramstein that visited it. It is first mentioned in 1225 and was until 1697 seat of the Palatine prince-electors. Today it is a wonderful ruin in Renaissance style made of red freestone.
You can get to the ruins located 80 meters above the city center by car or by a funicular leaving from the Kornmarkt. You can roam the castle and its courtyards and enjoy nice views on the river Neckar and the green hills behind it. A very long tradition is that once a year there are fireworks and the castle is lighted in the dark.
