The remains of a large, circular funerary monument, originally a mound, are still visible.
The mausoleum was recovered when the interior was emptied (after the second world war) and the site was demolished for laying via Prenestina. It has a diameter of about 41m, which makes it one of the largest mausoleums in Rome, after the Mausoleo di Augusto and the Monte del Grano.
None of the original marble decoration remains today and the work in tuff dates back to the restorations in the seventeenth century. The funerary cell, in a cruciform plan, is preserved at the centre, covered by a barrel vault and leads to a passage at the entrance.
During the Middle Ages, the monument was fortified and resembled a tower, which explains the monument’s name, only known to us through Renaissance engravings.
