Basilica of the Holy Cross in Jerusalem

This is one of the two main Jesuit churches in Rome, the other being the nearby Sant'Ignazio. The interior is Baroque art on steroids. Simply astounding.

This building housed the University of Rome from the middle of the 15th century until 1935. The splendid interior courtyard was created by Giacomo della Porta. The inside church of Sant'Ivo (see above) is one of the masterpieces of the architect Borromini.

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.

Built in the 9th century, this ancient basilica crowns the top of the Esquiline Hill. Tons of gold decorate the interior together with impressive mosaics (particularly when the floodlights are turned on), and there is a museum on the premises. If you are in Rome on Corpus Christi (Corpus Domini), which is the Thursday after the 8th Sunday after Easter, an early-evening service is held in San Giovanni by the Pope followed by a procession along Via Merulana to Santa Maria. Good opportunity for a close up view of the Pope. This is a very large church with lots to see, as for example, the main part of the church has two layers of mosaics and paintings high on the walls, the altar and apse are spectacular, and then there are several more or less large chapels you won't want to miss, including the one with the amazing golden baptismal font. Allow at least an hour if not an hour and a half or more to visit the interior, even if you do not take any special tours, and also allow time to view the exterior from all sides. Overall, at least 2 hours would not be too much time to allot.

The house in which the famous English poet John Keats succumbed to consumption, now preserved as a memorial to his life and that of his friend Shelley, both of whom are buried in Rome's Protestant Cemetery (see Testaccio).

This is a treasure-trove of art. There are a couple of paintings by Caravaggio: "The Crucifixion of Saint Peter" and "The Conversion of Saint Paul" (in a dim alcove to the left of the altar, both at right angles to the viewer, with a machine wanting €2 to switch on the lighting) together with a sculpture by Bernini, frescoes by Pinturicchio and mosaics by Raphael. Part of the Dan Brown tour, this church featured in Angels and Demons, although the Vatican did not allow filming inside.

Inaugurated in 217 AD and used until the 6th Century. The baths were big enough for 1600 bathers at a time. Impressive and well-preserved. Used for operas in summer months (see Opera di Roma for details) and was the location for the famous "three tenors" concert in July 1990, at the time of the World Cup (soccer).

Known properly as the Flavian Amphitheatre, this most famous of Roman landmarks takes its name from the giant statue of the emperor Nero that once stood near this location. The amphitheatre was capable of seating 50,000 spectators for animal fights and gladiatorial combats. It was a project started by the Emperor Vespasian in 72 and completed by his son Domitian sometime in the 80s. The Colosseum when completed measured 48 m high, 188 m in length, and 156 m in width. The wooden arena floor was 86 m by 54 m, and covered by sand.;Expect a long queue and an even longer wait. You can skip the queue if you decide to take a tour, but if you don't want a tour, you can STILL skip the queue. If you walk to the entrance for the Roman Forum, you can buy tickets there which allow you to bypass the queues. You can also buy tickets online. There are lots of people offering tours in English just outside the entrance to the Colosseum. Inside you can take a tour (English, Spanish, or German) every 30 minutes or so for an additional fee. The tours are given by knowledgeable archeologists, but they don't take you to any areas you couldn't visit on your own.

A relaxing place to sit and recover from the exertions of sightseeing. Permanent collection plus annual competition.

A pleasant fountain in an out-of-the-way square. It was originally meant to have four dolphins rather than turtles, but the dolphins proved to be too large for the water pressure, so the turtles were added as an afterthought.

Next door to Santa Croce. A collection of around 3000 pieces, although only a third of these are displayed.

Completed in 179 BC.
