Heidelberg's historic center is among the city's best-preserved businesses. Here are the university, the Church of the Holy Spirit, the Pazarniot Square. In this case, the main street is a pedestrian area surrounded by many historic buildings and small shops. Near the old town is the beautiful "Karl Theodor" bridge (known as the Old Bridge), built over the Neckar river, from which a wonderful view of the mountain and Heidelberg Castle opens.
