Dom Sankt BartholomÃ¤us (St Bartholomew's Cathedral), Frankfurt am Main, Germany.
This gothic-style cathedral was constructed in the 14th and 15th centuries on the foundation of an earlier church from the Merovingian time. Some of these ruins are still visible. Dom Sankt BartholomÃ¤us is the main church of Frankfurt and it has some historical significance. From 1356 onwards, kings of the Holy Roman Empire were elected in this church, and from 1562 to 1792, the Roman-German emperors were crowned here.
Is that the actual colour of the stone?
It is. Somehow I don't think it's limestone.
I wondered. I'd normally associate that sort of colour with sandstone, but limestone is much better for intricate carving.
