Yesterday we enjoyed a nice day at the thermal baths of this German city located very close to Basel, Mulhouse, and Freiburg. This was the first time we visited this town, and it turned out to be a picturesque place with a couple of fancy hotels, some restaurants, and full of baths due to the spring mineral waters it possesses. When we arrived in the town, we noticed from a distance the ruins of a castle, and when we were going back to the car, we noticed it again, so I grabbed my phone and took a picture. I was able to get a nice silhouette of the castle at this time of the year.
