These are windows of the Feudenheimschule in a district of Mannheim. Many schools were built in the first twenty years of the last century, and it shows in the style. Also, in our area of the country sandstone is an often used building material. This particular school was finished in 1913.
The detail in the top left photo is part of the crest of Mannheim, a wolf’s hook – a tool used to catch wolves and foxes in former times.

Just by looking at the windows, it definitely looks like a school! And a very clean school at that! 👍🏼

Indeed, clean and well designed. As for that wolf’s hook, you really need to get awfully close to use one of those! Thank you!
