On the day of Pentecost, every year, a shower of rose petals falls from above inside the Pantheon to conclude the celebration of Corpus Domini.

“The most beautiful remnant of Roman antiquity. A temple that has suffered so little that it appears to us as the Romans must have seen in their time ”, as the French writer Stendhal described it in the nineteenth century. Source of inspiration for the greatest architects of all ages and always admired for its beauty , harmony of lines and perfect calculation of the geometries of the masses , the Pantheon is in fact one of the best preserved examples of Roman monumental architecture.

The building is made up of a cylindrical structure preceded by a portico with Corinthian columns that support the pediment; the original inscription with the dedication to Agrippa is preserved on the frieze of the entablature. The large circular cell is surrounded by thick masonry walls and eight large pillars on which the weight of the characteristic hemispherical concrete dome, larger than that of St. Peter’s Basilica, is distributed. What is most surprising about the architecture of the Pantheon are its dimensions: the height of the building is equal to the diameter of the dome , just over 43 meters, a feature that reflects the classical canons of rational Roman architecture.
