Palazzo Muti Papazzurri

The palace was built in 1660 by De Rossi, a pupil of Bernini, probably on the occasion of the marriage of Pompeo Muti Papazzurri to Maria Isabella Massimo. The gallery was frescoed by Giovanni Francesco Grimaldi (1606-1680). An engraving from 1699 shows a large urban residence built around an open courtyard, accessed through a triumphal arch in the center of a structure connecting two side wings (forming a "U"). In the 18th century the housing estate was rented by the Stuart pretenders in Roman exile.

One of the major alterations that the building underwent was the addition carried out in 1919, when Benedict XV decided to move the Pontifical Gregorian University from Palazzo Gabrielli-Borromeo to a new, larger location. Palazzo Muti was thus sold - together with the part of Palazzo Colonna which dominated the other side of the square - to the Holy See which established the Pontifical Biblical Institute there until 1948.

The building became the property of Bruschi in 2005; later purchased by Beni Stabili SGR, today it is under mixed ownership.

The palace houses an extraordinary frescoed gallery inside. The frescoes are considered one of the best works of Giovan Francesco Grimaldi who painted them with extraordinary mastery in the mid-17th century.
