The Pantheon is a building in Rome, Italy. The building is circular with a portico of three ranks of huge granite Corinthian columns under a pediment.
A rectangular vestibule links the porch to the rotunda, which is under a coffered, concrete dome, with a central opening to the sky. Almost two thousand years after it was built, the Pantheon's dome is still the world's largest non-reinforced concrete dome.
The height to the oculus and the diameter of the interior circle are the same, 43.3 metres (142 ft).
It is one of the best preserved of all Roman buildings. It has been in continuous use throughout its history, and 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''; the square in front of the Pantheon is called Piazza della Rotonda.
