Rudolstadt is a town in the German Bundesland of Thuringia, close to the Thuringian Forest to the southwest, and to Jena and Weimar to the north. The former capital of Schwarzburg-Rudolstadt, the town is built along the River Saale inside a wide valley surrounded by woods. Rudolstadt was founded in 776 and has had municipal law since 1326. The town's landmark is the Castle Heidecksburg which is enthroned on a hill above the old town. Rudolstadt became popular through the Anchor Stone Blocks of the Toy Company Richter and porcelain factories, beginning with the establishment of the Volkstedt porcelain manufacture in 1762. Rudolstadt hosts Germany’s biggest folk, roots, and world music festival, TFF Rudolstadt (Tanz&FolkFest), taking place annually on the first full July weekend. The headquarters of the EPC Group, a global engineering and construction company, are in Rudolstadt. Since 2012 Rudolstadt hosts Gettingtough – The Race, Europe's hardest Obstacle Race.
