The Pantheon of Marcus Agrippa is one of the most famous and imitated architectural monuments in the world: a dome of perfect proportions resting on a series of elegant columns. Erected in 27 B.C. and rebuilt by Emperor Hadrian in 120, it is one of the best preserved ancient buildings in Rome. Its extraordinary dome is the largest concrete vault ever built.
