Scala Sancta

In the Middle Ages pilgrims on their way to St. Peter's had to pass through the Via dei Coronari in order to cross the Tiber at Ponte St. Angelo. The street got its name from the people who sold rosaries to the pilgrims. It follows the ancient Via Recta which led from what is today Piazza Colonna to the Tiber. In the 15th century Pope Sixtus IV initiated the construction of private buildings. Today, several houses dating back to the 15th and 16th century may be seen. House nr. 156/157 is said to have been the House of Fiametta, the mistress of Cesare Borgia.

Baroque church more noted for its position at the top of the Spanish Steps than it is for the church. Backdrop for numerous movies including Audrey Hepburn and Gregory Peck in Roman Holiday.

An ethnographic collection of around 60,000 pieces from European indigenous cultures. Documents evolution from the Palaeolithic age to the Iron Age.

More modern than most Roman churches: it was not started until 1873. This is Rome’s Episcopalian church. Some very interesting artwork, particularly the mosaics by Edward Burne-Jones of the Pre-Raphaelite school.

Completed in 1762 to a design by Nicola Salvi, this spectacular Baroque fountain features a mythological sculptural composition of Neptune, god of the sea, flanked by two Tritons: one Triton labours to control a violent sea-horse, the other controls a pacified creature, both symbolising the dual nature of the world's oceans. The location of the Trevi fountain marks the terminus of the ancient Aqua Virgo aqueduct, completed in 19 BCE in order to supply the Baths of Agrippa, and is so named on account of its position at the junction of three roads (tre vie). The legend says that one who throws a coin in the fountain shall one day return to Rome. The coins in the fountain are regularly collected to finance charities. The fountain has been made even more famous by the 1954 film, Three Coins in the Fountain, and by a famous scene in Federico Fellini's film La Dolce Vita. According to popular superstition and custom, throwing coins with one's right hand over one's left shoulder into the Trevi Fountain is a practice endowed with good luck. Throwing one coin ensures that the thrower will return to Rome; throwing two coins will ensure that the thrower will fall in love with a beautiful Roman girl (or handsome boy); throwing three coins, finally, ensures that the thrower will marry that girl or boy in Rome itself. The fountain is one of Rome's most famous attractions, but the square isn't exactly as large as St. Peter's, therefore it might be packed with crowds almost like at a rock festival. For this reason it's reportedly also a pickpocket hotspot, so do watch your pockets and bags here!

The Ghetto lies between the island in the River Tiber and the Theatre of Marcellus and includes Rome’s synagogue. It was established in 1555 as a result of a Papal Bull by Pope Paul IV that required all Jews to live in the area, considered one of the least desirable quarters of the city, as it was subject to constant flooding by the river. The area was originally enclosed by walls and gates that were only open during the day. With the end of the Papal States in 1870, the requirement that Jews live in the Ghetto came to an end. The walls were torn down in 1888 and much of the ghetto was demolished. However, there is still much to see, including walls of buildings that incorporate Roman ruins, and there are several good Jewish restaurants.

Home of the President of the Italian Republic, and the Quirinal Gardens. Built in 1573 as a papal summer residence, and has since also served as the residence for the pope and later for the king of Italy.

A medieval church dating from the 6th century and home to the Bocca della Verità (Mouth of Truth). The Bocca della Verità at the entrance to the church is thought to be a 1st-century manhole cover. It is believed that if you put your hand in the mouth and tell a lie, the hand will be bitten off. Queues for the privilege of risking this can get rather long. Don't ignore the church, which is a gem, and has a separate entrance. Its mosaic floor in the Cosmatesque style is more rustic and less intricate than some others (Santa Maria in Trastevere, for example), but its simplicity gives it a solidity not found in the more ornate styles. S.M. in Cosmedin has a fine medieval choir enclosure and the tallest medieval belfry in Rome.

A truly monumental stairway of 135 steps (similar to climbing eight flights of stairs), built with French funds between 1721 and 1725 in order to link the Bourbon Spanish embassy to the Holy See (still located in the piazza below), with the Bourbon French church (its monastery founded in 1495) above. Don't sit on them though, or eat, or push a baby stroller on them, or do anything else that might obstruct pedestrians, make them dirty, or cause additional wear and tear, or else you will have to pay a fine that ranges from €250 to €400.

In addition to Santa Maria in Cosmedin there is a lot to be seen around this piazza. Opposite the church is the round temple dedicated to Hercules Invictus (the Unconquered Hercules), and not far from that the rectangular Fortuna Virilis, both constructed in the 1st Century. Opposite, to the back of the piazza is the Arch of Argentari and behind that the church of San Giorgio in Velabro, the front of which was repaired after being damaged by a terrorist bomb in July 1993.

It was constructed to hold relics of the Passion of Jesus. They include two thorns of his crown, part of a nail and three small wooden pieces of the Cross. The authenticity of these relics is much disputed, however.

The remains of the ancient Roman archives, where Cicero and Seneca did research. Visible from the Forum and accessible through the Capitoline Museum.
