Schlossberg Graz
Steiermark
Schlossberg Graz is a prominent limestone hill rising 473 meters above sea level in the center of Graz, Austria. Historically a formidable fortress, it was never conquered but largely demolished in 1809 under the Treaty of Schönbrunn, sparing only the Uhrturm (clock tower) and Glockenturm (bell tower), which are now iconic city symbols. The site was transformed into a public park in 1839 by Ludwig von Welden, featuring extensive walking paths, cafés, and remnants of the fortifications such as bastions and a deep cistern known as the Türkenbrunnen. Visitors can enjoy panoramic views of Graz from the hilltop restaurants and terraces. Schlossberg also hosts cultural events like the Elevate Festival and offers unique attractions such as the Kasemattenbühne open-air stage and the Fairytale Express grotto railway for children. An extensive tunnel system beneath the hill, originally built during World War II as air-raid shelters, remains partially accessible. The Schlossberg funicular and elevators provide convenient access to the summit, making it a popular destination blending history, nature, and entertainment.

History
The Schlossberg fortress dates back to at least the 10th century, with major expansions in the 16th century by northern Italian architects.
It was renowned as one of the strongest fortresses in history, never conquered even by Napoleon.
In 1809, most fortifications were demolished following the Treaty of Schönbrunn, except for the Uhrturm and Glockenturm, which citizens saved by paying a ransom.
In 1839, Ludwig von Welden converted the ruins into a romantic public park.
During World War II, an extensive tunnel network was constructed inside the hill for civilian protection.
In 1999, the Schlossberg and the historic center of Graz were designated a UNESCO World Heritage Site.
