The Pantheon is one of the most incredible structures in all of Rome–and there’re plenty to choose from. Built around A.D. 125, the roof is still the world’s largest unreinforced concrete dome. It’s definitely withstood the test of time–wars, elements, disasters… I rarely do black and white photos, but it seemed appropriate this time. It feels like this picture could be a snapshot from any year in the life of this incredible building.
