Monuments in the Basilica of Santa Maria del Popolo
This elaborate Baroque monument set against the third pillar of the south aisle has several peculiarities. It is crowned by the coat-of-arms of Pope Nicholas IV (Girolamo Masci) but this medieval pope was buried in the Basilica of Santa Maria Maggiore. The monument in Santa Maria del Popolo was built for his late descendant, Count Masci-Ferracuti from Ascoli Piceno who was appointed to the Bishop of Vieste by Pope Sixtus V in 1589. He died in Rome in 1613 at the age of 60 years. He was buried with solemn pomp in a marble tomb in the basilica. The tomb was built by her niece, Anastasia Mascia and her husband, Marzio Elefantucci, a nobleman from Bologna. Under the pretense of honouring their uncle they built a monument for the most illustrious member of their family, Pope Nicholas IV whose name is mentioned twice in the funerary inscription.
Palazzo dei Convertendi
In 1937, during the construction of the Via della Conciliazione, the palace was demolished, and then reconstructed until 1941 west of Palazzo Torlonia. The relocation was supervised by Giuseppe Momo, the "court architect" of Pius XI (r. 1922–39), who after 1929 reshaped the new Vatican City. Momo collaborated in the reconstruction with Marcello Piacentini and Attilio Spaccarelli (the designers of via della Conciliazione). The architects moved the palace to an area that, until the mid-19th century, had been occupied by the houses of Soderini, an early Renaissance complex. The accuracy of the reconstruction allows the consideration of the rebuilt Palazzo dei Convertendi not as a new building, but as another phase in the centuries-old life of the edifice.
