Santa Maria del Popolo
Soon after its transfer to the prestigious Lombard Congregation Santa Maria del Popolo was reconstructed between 1472 and 1477 on the orders of Pope Sixtus IV. This was part of the ambitious urban renovation program of the pope who presented himself as "Urbis Restaurator" of Rome. The medieval church was entirely demolished and a new three-aisled, Latin cross shaped basilica was built with four identical chapels on both sides, an octagonal dome above the crossing and a tall Lombard style bell-tower at the end of the right transept. The result of this reconstruction was an early and excellent example of Italian Renaissance architecture in Rome. In spite of the many later changes the basilica essentially kept its Sistine form until today.
Cybo-Soderini Chapel (Santa Maria del Popolo)
The chapel was first mentioned in a contemporary document in 1530 as "capella Crucifixi" when the concession was renewed for Teodorina's son, Giambattista Usodimare (Cybo), the Bishop of Mariana. The bishop made an endowment of 30 gold scudi for the maintenance of the chapel instead of the house in the Borgo which had been destroyed during the Sack of Rome in 1527. In his will, dated to 1 December 1531 the bishop expressed his wish to be buried in the chapel and left the task to his heirs to erect a decent monument. At the time the chapel contained the burials of Teodorina and her husband. The bishop also donated valuable velvet and satin hangings. In 1555 the heirs, Cesare Cybo, the archbishop of Turin and Francesco Cybo renewed the endowment of the house in the Borgo which had been restored. The altar was consecrated on 18 October 1595.
