Michelangelo worked on a number of architectural projects at this time. They included a design for the Capitoline Hill with its trapezoid piazza displaying the ancient bronze statue of Marcus Aurelius. He designed the upper floor of the Palazzo Farnese, and the interior of the Church of Santa Maria degli Angeli, in which he transformed the vaulted interior of an Ancient Roman bathhouse. Other architectural works include San Giovanni dei Fiorentini, the Sforza Chapel (Capella Sforza) in the Basilica di Santa Maria Maggiore and the Porta Pia.[50]
