It is hot. It is 33C and on the cobbles in the old town it is even hotter. It feels like we are walking on a frying pan. Seeking shade and some reprieve from the heat wave instead of exploring the old town we decided to revisit the three big churches in Nuremberg. The beauty of these massive buildings is that they are cool inside about 15C. A new lens on the camera gives a different perspective of these great buildings.
