MDCXXXIV' Marc'Antonio and I Baptist, foppa brothers, having bought and destroyed the houses around the square to create the space for roads, spending just our money, in 1644. Giovanni Battista Foppa, Marc'Antonio's brother, became co-heir of a considerable fortune (heritage) consisting in properties and bank accounts in Rome and in Bergamo.
He administered the inheritance with his brother until 1622, when he entered the Congregation Oratorio San Filippo Neri.
In 1643 he became Archbishop of Benevento and because of the distance, it was no longer possible to jointly administer the property. In 1658 it was divided and the house in Rome became exclusive property of Marc'Antonio.
In July 7th, 1673, Giovanni Battista Foppa died. Marc'Antonio became a tenant for half of the assets in Rome and in Bergamo. Also, Marc'Antonio died shortly after in December 18th, 1673 and according to his bequest, all the assets were assigned to the poor maidens of the parish of St. Biagio della Fossa incorporated with the parish of St. And St. Thomas in Parione Celso, administered by the Cardinal Vice-Chancellor pro tempore.
Opera Pia Foppa, still owner of the building in 1845, extended the Palace, at that time composed of 10 rooms on the first floor, 14 rooms on the second one, 12 on the third and 14 on the fourth. After that it became the property of Giuseppe de Rossi Mutarelli’s son, who lived in Via della Pace 35.
Inside the building it is still kept the crest marble of Foppa Family, representing a hay rake in a hand and a cornflower in the center. The original colours were gold on a blue background. Unfortunately from the original furnishings of the Palace there have remained only some little fragments of frescoes and stained glass ceiling beams in some rooms, but the inventory drawn up at the time of Marc'Antonio Foppa’s death, was richly adorned with furniture, dishes, silverware, gold, paintings of religious subjects and various portraits, which together constituted a valuable collection. Some of these paintings were made by famous artists like Correggio, Tiziano and Zuccari.
