The Elisabethenkirche is another one of Basel’s churches. It is located at the theatre (near the Barfuesser Place), right behind the Tinguely Fountain.
The thing in the front is a sculpture. Unfortunately, I don’t remember by which artist. Actually, I don’t like it (I call it the Wall of Rust), and others must not like it, since it’s often used to graffiti.
(Just recently, I read that the rust covering was intentionally put there by the artist, but it is in danger because of the spray paint and because some men obviously can't wait for the next toilet.)
