THE PANTHEON is the largest and oldest cement dome still in existence. the present structure was built on the site of an earlier temple commissioned by Marcus Agrippa during the reign of Augusta Caesar. After that temple burnt down, Emperor Hadrian rebuilt it and kept the original commissioning inscription at the top. It was probably rededicated in 126 A.D.
