And There is the Pantheon

We saw from a view from the hills of Rome a huge flattened dome building and initially didn't think it the Pantheon. Notice the scale of the columns compared to humans.  Some nice original detail from the back. The hole in the center of the dome has a diameter of 27 feet (not visible in photos). It dates back to Emperor Hadrian.  Amazing it is still standing. https://en.m.wikipedia.org/wiki/Pantheon,_Rome
