Santa Maria del Popolo
The architect or architects of this innovative project remain unknown due to a lack of contemporary sources. Giorgio Vasari in his "Lives" attributed all the important papal projects in Rome during Sixtus IV to a Florentine, Baccio Pontelli including the basilica and monastery of Santa Maria del Popolo. Modern researchers deemed this claim highly dubious and proposed other names among them Andrea Bregno, a Lombard sculptor and architect whose workshop certainly received important commissions in the basilica. The fundamental differences between the façade and the interior suggest that maybe more than one architect was working on the building.
Bevilacqua dynasty
The Bevilacqua family reconstructed and dedicated Saint Peter's Church in Cantalovo of Bevilacqua to celebrate their victory. The original church was built in the early 900's, and the reconstruction was begun in 1142 and completed in 1161. The reconstruction followed the technique of early Roman buildings and it is made of bricks baked in a kiln. Several frescoes decorate the inside walls of the church which are from the late 14th century.
Over the outside door of Saint Peter's Church, a barbaric inscription is carved on a white Verona marble block which says, "This is the ancient parochial church of Porto reconstructed in 1161 by the work of Balduino, under the rule of Emperor Frederic Barbarossa". Balduino was most probably Balduino della Scala (b. - 1169) who was the founder of the della Scala dynasty and rulers of Verona. The della Scala were well known in the area hence no title to his name was necessary. In the Archives of the Capitolare of Verona, a document is still preserved from 1159 granting additional "territory to Guglielmo Bevilacqua by King Frederic Barbarossa witnessed by Balduino for loyalty and service to the della Scala family, rulers of Verona."
