Rome the Complete Tour

The Colosseum or Coliseum, also known as the Flavian Amphitheatre or Colosseo, is an oval amphitheatre in the centre of the city of Rome, Italy. Built of travertine limestone, tuff (volcanic rock), and brick-faced concrete, it was the largest amphitheatre ever built at the time and held 50,000 to 80,000 spectators. The Colosseum is situated just east of the Roman Forum. Construction began under the emperor Vespasian in AD 72 and was completed in AD 80 under his successor and heir, Titus. Further modifications were made during the reign of Domitian (81–96). These three emperors are known as the Flavian dynasty, and the amphitheatre was named in Latin for its association with their family name (Flavius). The Colosseum could hold an estimated 50,000 to 80,000 spectators at various points of its history over the centuries, having an average audience of some 65,000; it was used for gladiatorial contests and public spectacles such as mock sea battles (for only a short time as the hypogeum was soon filled in with mechanisms to support the other activities), animal hunts, executions, re-enactments of famous battles, and dramas based on Classical mythology. The building ceased to be used for entertainment in the early medieval era. It was later reused for such purposes as housing, workshops, quarters for a religious order, a fortress, a quarry, and a Christian shrine. Although substantially ruined because of earthquakes and stone-robbers, the Colosseum is still an iconic symbol of Imperial Rome and is listed as one of the New7Wonders of the World. It is one of Rome's most popular tourist attractions and also has links to the Roman Catholic Church, as each Good Friday the Pope leads a torchlit "Way of the Cross" procession that starts in the area around the Colosseum. In 2018, it was the most popular tourist attraction in the world, with 7.4 million visitors.

One of Rome's most characteristic Baroque squares, Piazza Navona still has the outline of the Roman stadium built here by Emperor Domitian. It was still used for festivals and horse races during the Middle Ages, and was rebuilt in the Baroque style by Borromini, who also designed the magnificent series of palaces and the church of Sant'Agnese, on its west side. Its facade, campanile, and dome highlight the way Baroque architecture weaves convex and concave surfaces, gables, windows, columns, and piers into a unified design. In the crypt of Sant'Agnese are Alessandro Algardi's 1653 The Miracle of St. Agnes and the remains of a Roman mosaic floor. Sant'Agnese provided a model for Baroque and Rococo churches in Italy and elsewhere.

The Trevi Fountain is a fountain in the Trevi district in Rome, Italy, designed by Italian architect Nicola Salvi and completed by Giuseppe Pannini and several others. Standing 26.3 metres high and 49.15 metres wide, it is the largest Baroque fountain in the city and one of the most famous fountains in the world. The fountain at the junction of three roads (tre vie) marks the terminal point of the "modern" Acqua Vergine, the revived Aqua Virgo, one of the aqueducts that supplied water to ancient Rome. In 19 BC, supposedly with the help of a virgin, Roman technicians located a source of pure water some 13 km from the city. (This scene is presented on the present fountain's façade.) However, the eventual indirect route of the aqueduct made its length some 22 km. This Aqua Virgo led the water into the Baths of Agrippa. It served Rome for more than 400 years.
