Column of the Immaculate Conception, Rome

The Column of the Immaculate Conception is a nineteenth-century monument in central Rome depicting the Blessed Virgin Mary, located in what is called Piazza Mignanelli, towards the south east part of Piazza di Spagna. It was placed aptly in front of the offices of the Palazzo di Propaganda Fide which houses the Congregation for the Evangelization of Peoples.

Since December 1953, Pontiffs have visited the monument annually and offered a bouquet of flowers at the base of the column with help of Roman firemen commemorating the Feast of the Immaculate Conception.
