However, when the Papal residence moved from the Lateran to the Vatican palace, this basilica lost importance. In 1564, Pope Pius IV entrusted the basilica and the surrounding buildings to the Augustinians, who still serve it. The interest in the history of this complex renewed in 1913, thanks to the work of the Fine Arts Superintendent Antonio Muñoz. Once the building became an orphanage, the Augustinian nuns put a revolving drum by its entrance which was used as a deposit "box" for unwanted babies. The apse contains the frescoes (1630) by Giovanni da San Giovanni of the four patron martyr saints, Severo, Severiano, Carpoforo e Vittorino. The altarpiece on the left nave of "S.Sebastiano curato da Lucina e Irene" was painted by Giovanni Baglione. The second courtyard holds the entrance to the "Oratorio di San Silvestro", with frescoes of medieval origin, as well as others by Raffaellino da Reggio. Santi Quattro Coronati belongs to the titular churches of Rome from at least the end of 6th century. The current Cardinal Priest of the "Titulus Ss. Quattuor Coronatorum" is Cardinal Roger Mahony, Archbishop Emeritus of Los Angeles. Among the previous titulars are: Pope Leo IV (847), King Henry of Portugal, who, in 1580, donated the magnificent wooden ceiling, and Pope Benedict XV (1914). The full list is known only from the pontificate of Pope Benedict XII (1334-1342):   In 2002 art historian Andreina Draghi discovered an amazing display of frescoes, dating back to 13th century, while restoring the Gothic Hall of the monastery. Most of the scenes were well preserved under a thick layer of plaster, and represented the Twelve Months, the Liberal Arts, the Four Seasons and the Zodiac. The image of King Solomon, a pious and a judge, painted on the northern wall led scholars to argue the room was meant to be a Hall of Justice. Plaster was possibly laid after 1348 Black Death for hygienical reasons, or perhaps in the 15th century, when the Camaldolese left the monastery.
