The more we get around the more of these things we notice. We walk down the same path time and time again and always find something new. Nuremberg is quite amazing from that perspective, and this is just a small part of the old town.
It seems that just about every old building in the city has its own set of interesting details. Sculptures, sun clocks, reliefs, turrets and towers, caps and carvings. One of the more perplexing ones is a turret capping on St. Lorenz Church and it is that of a monkey reading a book.
