Grazer Schlossberg

According to the Guinness Book of World Records, the Schlossberg was the world's strongest fortress ever. Unfortunately, Napoleon commissioned the demolition of the fortress and only a few buildings were saved by locals. The Schlossberg is still worth a visit nonetheless. Whether you come for attractions and events within the mountain (slide, performances) or you want to enjoy the view over Graz, the Schlossberg remains a visitor attraction until this day.
