The Pantheon is one of the best preserved Ancient Roman building. Originally built for political purposes, it is now a church that also houses the tombs of painter Raphael as well as two Italian kings Vittorio Emanuele II and Umberto I. The dome of the Pantheon contains an oculus, one of two light sources of the structure. Squares that are evenly sunk along the sides of the dome create dynamic shadows that change with the angle of the sunlight shooting in from the oculus. I wonder what happens when it rains though.
