Recently I was in Lyon, France, and got to stay in the lovely apartment of a friend in the old part of the city. The ground floor was built in the Middle Ages; consecutive floors were built during the Renaissance. The stones surrounding the doors and windows bear the identifying mark of the stone cutter. Hundreds of years of human history amidst these walls; thousands of years more are layered beneath them.
I painted this tiny sketch of the view from the kitchen (fifth floor), and left it with the key.
