The Pantheon, Rome Italy

In a continuing desire to get people to look up, I post this photo of the ceiling of the Pantheon in Rome. It has an open circle in the center to allow smoke out and fresh air in. It also lets rain in and thus there are drain holes in the middle of the floor.  This is an amazing building and is often filled with a wide variety of tourists and pilgrims. It is central to things and a good stop. (Photo by Marietta McLellan)
