The Church of the Holy Spirit (Heiliggeistkirche, map) is the most famous church in Heidelberg. It stands in the middle of the market place in the old center of Heidelberg not far from the Heidelberg Castle. The steeple of the church, rising above the roofs, dominates the town.
On the northern side of the Neckar is located the Heiligenberg (Saints’ Mountain), along the side of which runs the Philosophers’ Walk (Philosophenweg, map), with scenic views of the old town and castle. Traditionally, Heidelberg’s philosophers and university professors would walk and talk along the pathway.
One of the biggest tourist attractions is the Christmas market during the winter time.
