A central cloister with garden and fountain forms the heart of campus. The two basins of the ancient fountain are fed by the "Acqua Felice" aqueduct, one of the aqueducts of Rome, and the first new aqueduct of early modern Rome, completed in 1585 by Pope Sixtus V whose birth name was Felice Peretti. It also feeds the fountain by Giovanni Battista Soria (c. 1630) at the entrance to the "Angelicum's" walled garden, and the fountain under the stair below the University's "portineria" or porter's lodge before coursing across the Quirinal hill to its terminus at the Moses fountain or Fontana dell'Acqua Felice on the "Via del Quirinale".
