The Church of the Most Holy Name of Mary at the Trajan Forum (Italian: Santissimo Nome di Maria al Foro Traiano, Latin: Ss.

The feast of the Holy Name of Mary was instituted by Pope Innocent XI after the victory of the Austrian-Polish armies under the command of John III Sobieski over the Turks at the Battle of Vienna in 1683.

Every year up until 1870, the members would walk in procession on the Feast of the Holy Name of Mary to the church of Santa Maria della Vittoria, stopping at the Quirinal Palace for the pope's blessing.

[3] In 1694, the confraternity moved to San Bernardo a Colonna Traiani, but the next year, realizing that they needed to build a new church, they acquired the adjacent plot and had Santissimo Nome di Maria built by the French architect Antoine Derizet (1736-1741).

Two double-head eagles with triple crowns are on the flanking pilasters the of the high altar in memory of the special protection that the Emperor Leopold I wanted to grant from himself and his heirs.
