The Pantheon is a building which was originally built by Marcus Agrippa as a temple to all the gods of Ancient Roma, and rebuilt in the early 2nd century AD. Almost two thousand years after it was built, the Pantheon's dome is still the world's largest unreinforced concrete dome. The height to the oculus and the diameter of the interior circle are the same, 43.3 metres. It is one of the best preserved of all Roman buildings and has been in continuous use throughout its history. Since the 7th century, the Pantheon has been used as a Roman Catholic church dedicated to "St. Mary and the Martyrs" but informally known as "Santa Maria Rotonda." Since the Renaissance the Pantheon has been used as a tomb. Among those buried there are the painters Raphael and Annibale Carracci, the composer Arcangelo Corelli, and the architect Baldassare Peruzzi.
