Mosaic in Cologne
The Kölner Dom or Cologne cathedral is an art gallery. Like all famous European cathedrals it has its fair share of Glass paintings, ceiling paintings and sculptures. But the most striking part for me was the intricate mosaic flooring. Very different and historic pieces are mosiaced all over the cathedrals flooring. Additionally there are patterned mosaic flooring. So it is not just history in pieces but art as well.
