On the North banks of the river Neckar you can see the silhouette of the Heiligenberg with a height of 440 m. The Philosophenweg (philosophers' walk) that lies at its foot offers many good viewpoints on Heidelberg. Those who want to see Heidelberg from a higher point should make a trip to the top of the Heiligenberg. Directly beside is the ruin of the Abbey of St. Stephan.
500 m down the road is the Thingstätte, an amphitheater dating from the Nazi period. Following the foot path 200 m to the second peak of the hill, there is a piece of history that is really worth seeing: the ruins of the Abbey of Michael. From here you have an impressive view over the Neckar valley.
