Nestled on the banks of the Tiber, this towering mausoleum turned fortress whispers tales of its many transformations through history. Originally commissioned by Emperor Hadrian as a grand tomb for himself and his family, it later morphed into an imposing papal fortress and even a prison.

Ever resourceful, a secret passage called the Passetto di Borgo links it to the Vatican, once offering popes an emergency escape route. Today, visitors can explore its intriguing layers, uncovering stories etched into its very stones.
