The Lorettoberg, also known as Josephsbergle in Freiburg, is a mountain ridge in the South-West of the Wiehre district in the city of Freiburg im Breisgau in Germany. The mountain, with its elevation of 384,5 meters above sea level, is wooded at its peak. It divides the district Unterwiehre-Süd and borders the Vauban district in the West. 500 meters north of the “peak” there is a high spur 348m above sea level, next to which the eponymous Lorettokapelle is located. The name derives from Loreto, the second biggest Italian (Mary-) pilgrimage destination, after the St. Peter's Basilica in Rome. The Schloss-Café is located at the top of the mountain making the Lorettoberg a popular destination for a getaway, strolling and a local recreation area.The eastern main edge fault of the Upper Rhine Rift drags through Lorettoberg and the Höllentalbahn runs through the mountain via the Lorettotunnel. When the tunnel was built, a “geological window” was left open, through which the fault can be seen and where further decline of the Upper Rhine Rift can be measured.BuildingsThe 22,6 meter high Hildaturm has been standing on the subpeak at the north side of the main summit since 1886. It is built in Medieval Bergfried style and is a memorial of the day Princess Hilda Charlotte Wilhelmine of Nassau the last Grand Duchy of Baden moved to Freiburg following her marriage to Fredrick II, Grand Duke of Baden. The Hildaturm was used as an observation tower for aerial survaillance during the World War II. During summer, the 19.86 meter high observation deck is open to public on selected weekdays.
