Looking for a window frame?

Good day,

I am completely new here and would like to ask a question right away.
(Is there generally a members' forum here to introduce oneself or similar?)

My question:
I recently took the following picture during a renovation of an old building in Breslau:


What are these "molding stones" called? Can anyone help me with this?

Thank you very much

These are cornice stones, but using [Formstein] is also correct ;)

You can find our introduction forum at the very bottom (sorry, but I currently can't link with Tapatalk :()

But still, welcome!

Here you go :)

Thank you for the response.

Where can you get this type of stones? I only ever find small manufacturers who offer something like this handmade for monument protection objects.
In the picture I posted at the beginning, they are more like... well..."prefabricated parts."

Anyone have an idea?
