Address: piazza di Spagna

The column had been inaugurated the 8th September 1857 from Pious IX, as a commemorative monument of the proclamation of the Immaculate dogma.
It originates from the Campo Marzio (nearby the homonym monastery) where it had been discovered in the 1777 and it is 11,81 meters tall.
It is in veined marble "cipollino" and it seems that it has never been previously set in use, but it has lain in one marble workshop. The setup was of the arch. Luigi Poletti, which superimposed it a bronze statue of the Virgo and adorned it at the base with a tall bronzy grate that has function of reinforcement.
At the four sides of the high plinth there are four statues of prophets. It was decided to put it in the open space between the palace of Propaganda and the one of Spain, in the full perspective of the Babuino's way.
The monument, conceived from the Poletti architect, is the last great emergence that has been placed in the public squares of Rome after the dissemination of ancient obelisks, after the two columns coclide and after the column of the Virgo set in front of the S. Maria Maggiore façade.
