Baden Baden, a small German town located in the Os Valley, on the edge of the northwest Black Forest. The city stretches along the valley, backed by green hills, facing the beautiful water, and the scenery is charming. In the first century AD, ancient Romans found mineral springs in the valley with temperatures of up to 69 degrees. So they started building a large bathing place and called it Aquae, which means bathing. In German, Baden means bathing or swimming. We didn't have a hot spring bath here, but we were looking for Baden Baden's past and present in the heavy rain.
