The Colosseum, is one of the most important works of Roman engineering. The original name was the Flavian Amphitheatre, is situated in the centre of the city of Rome, Italy, and it is the largest ever built in the Roman Empire.
Building started in 72 AD under the emperor Vespasian and was completed in 80 AD under Titus, with further modifications.
The Colosseum was used for gladiatorial contests and public spectacles such as sea battles, executions, animal hunts, and dramas based on Classical mythology.
In the early medieval era the building ceased to be used for entertainment. It was later reused for different purposes like housing, workshops, quarters for a religious order, a fortress, a quarry, and a Christian shrine.
The Colosseum is a symbol of the Roman Empire. It is probably the most important tourist attractions.

Sistine Chapel is the official residence of the Pope in Vatican City. It is famous for its architecture and its decoration painted throughout by Renaissance artists including Michelangelo, Sandro Botticelli, Pietro Perugino, Pinturicchio and others.
Under the Pope Julius II, Michelangelo painted 1,100 m2 of the chapel (between 1508 and 1512).
The chapel takes its name from Pope Sixtus IV, who restored the old Cappella Magna between 1477 and 1480. During this period a team of painters that included Pietro Perugino, Sandro Botticelli and Domenico Ghirlandaio created a series of frescoed panels depicting the life of Moses and the life of Christ, offset by papal portraits above and trompe l’oeil drapery below.
Since the time of Sixtus IV, the chapel has served as a place of both religious and functionary papal activity. Today it is the site of the Papal conclave.
