Santa Marta al Collegio Romano, Former church in Piazza del Collegio Romano, Rome, Italy

Santa Marta al Collegio Romano is a former church near Piazza del Collegio Romano in central Rome, with a stone facade and rectangular windows on the upper level. The interior follows a single-nave layout with a semicircular apse and square side chapels opening onto the main space.

Ignatius of Loyola founded the Casa di Santa Marta in 1543 to rehabilitate women described as "malmaritate"—married women living in public sin—anticipating later Tridentine measures on former prostitutes. After his death the house became a convent; by 1560 it passed to Augustinian nuns. Cardinal Borromeo renewed the church, Eleonora Boncompagni did so in 1673, and Carlo Fontana's reconstruction preceded its consecration in 1696. It was deconsecrated under Napoleon and became a military warehouse in 1870; the Italian state confiscated monastery and church in 1872.

The church is named for Saint Martha, regarded as patroness of married women, reflecting the purpose of the house Ignatius of Loyola founded here in 1543. Today the deconsecrated space hosts conferences, exhibitions and concerts, and is owned by the Ministry of Cultural Heritage. The former monastery houses Rome's First Police District.

The building sits in central Rome within walking distance of the Pantheon and many other historic sites, making it easy to combine with a broader visit to the area. Since it now functions as a cultural center, it is worth checking in advance what events are scheduled before planning your visit.

The ceiling fresco was painted by Baciccio, the same artist behind the celebrated ceiling of the Jesuit church Il Gesù in Rome, which shows how closely this building was connected to that artistic circle. Part of the former monastery complex today houses Rome's First Police District.
