The Pantheon «temple of all gods» a building of ancient Rome located in the historic center, built as a temple dedicated to all past, present and future divinities. It is composed of a circular structure joined to a portico in Corinthian columns (eight at the front and two groups of four in the second and third row) that support a pediment. The large circular cell, called rotunda, is surrounded by thick masonry walls and eight large pillars on which the weight of the characteristic hemispherical concrete dome is distributed, which houses at its apex a circular opening called oculus, which allows the illumination of the internal environment. The height of the building calculated at the oculus is equal to the diameter of the rotunda, a feature that reflects the classical criteria of balanced and harmonious architecture. Almost two millennia after its construction, the dome of the Pantheon is still today one of the largest domes in the world, and the largest built in Roman concrete.
