May 11th, 2009, at 5.38 pm. Have tweaked the colour a little.
The building is as wide as it is tall and rainwater coming in through the open window in the dome is drained off by a convex floor.The building of such a dome was made possible by the invention of concrete. The cassettes are thinned out to remove some of the weight. It was built during the reign of Hadrian around 120 AD and is the oldest building in Rome that has been in continuous use until today. It was given to the Pope Bonifatius IV in 609 as a gift from the reigning Bysantine emperor Fokas.
It used to be consecrated to “All Gods and Goddesses”, but is now converted into a Christian Church.
