This complex was the original home of the prince-bishops, beginning in the 13th century. The oldest buildings, including the Marienkirche (Church of the Virgin Mary) on the hilltop, date from around 700, although excavations have disclosed evidence that there was a settlement here in the Iron Age, 3,000 years ago. In addition to the rough-hewn medieval fortifications, there are a number of Renaissance and baroque apartments. Tours in English, held at 3 pm, meet at the Pferdeschwemme. To reach the Marienberg, make the fairly steep climb on foot through vineyards or take Bus 9, starting at the Residenz, with several stops in the city. It runs about every 40 minutes from April to October. From April through October, tours around the fortress itself are offered for €2 per person, starting from the Scherenberg Tor.
