You can walk through the promenade to a viewing platform, which also overlooks the city of Heidelberg. No wonder the poet Goethe "has lost his heart in Heidelberg". Mark Twain said that Heidelberg is the most beautiful place he has ever been. Come here is really attracted to the romantic atmosphere of Heidelberg. Heidelberg in the green mountains and green waters, I like the stone bridges, castles and white walls and red tiles of the old town buildings. Every place is full of romance and charming colors.
