Hi Mateusz,

thanks for your message.

These are large historical sandstone blocks which you can find everywhere around Dresden and the surrounding. Like these ones: https://www.historischebaustoffe-dresden.de/mauerbau/sandsteinbloecke.html

I don't think that any of the above categories do really fit. The closest would probably be sett with material=sandstone but I'm not really satisfied with this. What do you think?

Greetings
Alex
