1. Basilica of Santa Sabina all'Aventino, Italy

Built on the Aventine Hill in Rome by a Dalmatian priest between 422-433 AD, Basilica di Santa Sabina all'Aventino has stood out remarkably over the centuries, still retaining its original architectural plan. In addition, it still hosts the services of the Catholic Church, giving it a precious historical load.

2. Theatre of Marcellus, Italy

The construction of the Theatre of Marcellus, once known as the largest open-air theatre in Rome, was completed in 13 BC, during the reign of Octavian Augustus, who named it after his nephew, Marcus Claudius Marcellus. Although the building is over 2,000 years old, the apartments arranged on its upper floors are still inhabited, giving the tenants the unique feeling of being surrounded by centuries of history. They are, at the same time, proof of the flawless ability of the architects of the time.
