Pantheon

The Pantheon was formerly a temple in Rome on the site of a former temple built by Marcus Agrippa during the reign of Augustus from 27 BC to 14 AD, the Pantheon became a Catholic church in Rome starting in the year 609.

The cylinder-shaped structure has a portico with eight huge granite Corinthian columns in the top tier and two sets of four columns beyond, all arranged under a pediment. The porch and the rotunda, which has a central opening to the sky and is covered by a coffered concrete dome, are connected by a rectangular vestibule. The Pantheon's dome continues to be the biggest unreinforced concrete dome in the world, over two thousand years after it was constructed. The inside circle's diameter and height to the oculus are also 43 meters (142 ft). The words "M.AGRIPPA.L.F.COS.TERTIUM.FECIT" are displayed in bronze on the facade. It means that Marcus Agrippa, son of Lucius, third-time consul, has built this.

The Pantheon is among the most well-preserved of all Ancient Roman structures, largely as a result of its continuous usage throughout Rome's history. It has been the church honoring Saint Mary and the Martyrs since the seventh century. The Pantheon is a public building that is overseen by the Polo Museale del Lazio, a division of the Italian Ministry of Cultural Heritage, Activities, and Tourism.
