A round 4th-century mausoleum built for Constantine's daughter Constantina, one of the best-preserved late-antique buildings in Rome, with its original ceiling mosaics and a ring-shaped ambulatory around the central dome. It sits in the Sant'Agnese fuori le Mura complex on Via Nomentana, a residential area few visitors reach.
