Galleria Borghese

Although started in the 2nd century, San Callisto has had many more recent burials, including 16 popes. The burial arcades are almost 20 km long.

Unusual ancient Roman theatre with apartments built on top.

Built in 81 AD by the emperor Domitianus in dedication to his brother Titus, who died earlier that year and reigned as emperor from 79-81, overseeing the opening of the Colosseum in 80 and the eruption of Mt Vesuvius the previous year.

An example of urban planning that goes back to Pope Julius II, who, in 1508, envisioned it as a street that would connect all major government buildings. It is around a kilometer long and is in a straight line, an unusual feature for the time. It is lined with some interesting palaces but these days is more known for its antique shops. Via Giulia runs parallel with and one block from the River Tiber.

Casal Rotondo is the biggest mausoleum on the Appian Way, at about the sixth mile. It now incorporates a small private villa, originally a farmhouse. It is not known for whom it was built. The wall of fragments next to it, constructed by Luigi Canina, has ruins referring to the Cotta family but this family is now believed to not be associated with the Casal Rotondo.

Parco Savello is the name of the grounds and orange grove next to the Santa Sabina church at the top of the Aventino and also where you have one of the best views of the city. Families gather here to sit under the dozens of orange trees. The "Giardino degli Aranci" is also a well known spot for lovers at night. The best views are arguably from Janiculum hill, just across the Tevere (Tiber) river. Immediately below you, the Tiber snakes its way through the city, and directly beyond it you can see the lively medieval quarter of Trastevere. Beyond that is the majestic dome of St. Peter's Basilica, with the historic centre of Rome visible to the right.

They are posted at entrances to the Vatican City to provide security and protect the Pope. They wear very colourful clothing, similar to the uniforms worn by Renaissance-era soldiers. The Pontifical Swiss Guards is also the smallest and oldest standing army in the world, founded in 1506 by Pope Julius II. The origins of the Swiss guards, however, go back much further as the popes had regularly imported Swiss mercenaries during the 1400s.

Good collection of Renaissance and Baroque art, including by Velasquez, Titian, Raphael, and Bernini, all owned by the Doria Pamphilj family. Excellent audio guides really bring the paintings to life.

A 5th-century basilica, simply and attractively decorated. The wooden door, of which 18 carved panels of scenes from the Bible survive, is believed to date from the church's construction.

Rome's museum of contemporary art, housed in a former industrial complex. Rotating exhibitions, each one usually lasting about 4 months. The MACRO Testaccio exhibition space is located in Aventino-Testaccio.
