One of the most prestigious and historic thermal spas in Germany can be found in the southeastern part of the country. Located at the eastern border of the Upper Rhine Graben, the city is nestled between vineyards, forests and the plains of the Rhine valley; where, the River Oos leaves the mountains of the Black Forest. The hot springs are known at least since Roman times, and the spa was a social center for the European nobility in the 19th century (the “Belle Époque“). Baden-Baden is still considered as a top place for balneological treatment and society events
