The Trinkhalle (drinking hall) hosts the tourist information office and one of Baden-Baden's thermal springs, the Friedrichsquelle. Hot spring water is constantly running from the tap and may be taken for free. Bring a bottle or a cup, or get a plastic cup for 20 cents there.
It is recommended not to drink more than 400 ml of this water per day. Well, I assume you won't want more. The taste is strange, rather salty. Give it a try, though - this is one of the things one simply HAS to do when in Baden-Baden...
The 19th century hall was built as a shady refuge where people could walk up and down, talk, watch and be watched while sipping their water.
The paintings on the walls show scenes from old regional legends and fairy tales.
The relief in the gable above the main entrance (photo 5) shows the healing powers of Baden-Baden's springs. From left to right, sick and old people are brought to the spring, which is impersonated by the nymph in the centre who is giving water to a little child and his mother. On the right side, healthy and happy young people are dancing and playing with their children.
