Donato Bramante
The apse was designed by Donato Bramante. The oldest stained glass window in Rome can be found here, made by French artist Guillaume de Marcillat. Pinturicchio decorated the vault with frescoes, including the "Coronation of the Virgin". The tombs of Cardinals Ascanio Sforza and Girolamo Basso della Rovere, both made by Andrea Sansovino, can also be found in the apse.
