While we were in Rome, we visited the Pantheon from which was a former Roman Temple and is now a church, in Italy. It was commissioned by Agrippa during the reign of Augustus (27 BC – 14 AD). Completed by the emperor Hadrian about 126 AD.
The exquisite building is circular with a portico made of large granite columns with a rectangular vestibule that links the porch to the grand rotunda under the dome with a central opening to the sky. I can see why Michelangelo visited so often. Certainly would be inspirational.
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 rotunda and the diameter of the interior circle are the same, 142 feet (43 m).
It is one of the best-preserved of all Roman ancient buildings because it has been in continuous use throughout its history, and since the 7th century.
The Pantheon has been used as a church dedicated to St. Mary and the Martyrs or in Latin “Sancta Maria ad Martyres” but informally known as “Santa Maria Rotonda”.
The square in front of the Pantheon is called Piazza Della Rotunda.
The Pantheon is Rome’s one of two most popular tourist destinations with over 4.2 million tourists per year, making them the world’s 37th most visited destination.
