You will find the ruins of ancient Rome throughout the city. One reason is that re-use has preserved many of the magnificent structures of Imperial Rome. The Temple of Hadrian is a fascinating example of this. Although the structure as a whole no longer stands, you can easily see the wonder of the building, for the large columns and the entablature survive in a modern building. The remaining wall of the Temple of Hadrian sits in its own Piazza, so there is plenty of time t

Michelangelo repurposed the ruins of Emperor Diocletian's baths into the church Santa Maria degli Angeli, where the massive scale of ancient structures is layered into a beautiful basilica. The Termini train station, named for "baths," is across the street, and Piazza della Repubblica, a common filming scene, is directly outside.

A visit to the Baths of Caracalla, though in ruins, reveals the immense scale of Roman construction and its core brickwork. Constructed in the early 200s AD, these baths were used until 500 AD and served as a place for bathing, exercise, relaxation, and possibly included a library. The site is easily accessible by taxi or bus.
