1. Colosseum (from USD 53.85)

At 188 meters (617 ft) in length, 156 meters (512 ft) in width, and 57 meters (187 ft) in height, the Colosseum is colossal. The imposing structure was built between 70 and 80 AD, during the Flavian Dynasty. This is why initially it was called the Flavian Ampitheatre. It was changed to its current name when a statue of Nero, ‘The Colossus of Nero’, was erected at the entrance of the Domus Aurea, a palace built after the Fire of Rome.
The Colosseum held about 65,000 people at the time, and the massive amphitheater was used for gladiator fights, recreations of famous battles, theatrical productions, prisoner executions, and animal hunts. For more than 500 years, it remained in active use, with the final recorded games held in the 6th century. Today, the Colosseum holds the distinction as one of the Seven Wonders of the Modern World and receives six million tourists annually. So, it gets awfully crowded, which means you’ll want to get here early or get a ticket that allows you to skip the long lines.

4. Giotto's Bell Tower

The bell tower was named after its architect, Giotto, although he only worked on it for three years.

7. Pantheon (from USD 27.3)

The Pantheon is one of the most preserved buildings and also one of the best places to visit in Rome. It’s also a testament to engineering and architecture. It was constructed between 118 and 125 AD as a replacement to the pantheon Marcus Agrippa, which was destroyed by fire in 80 AD. Although initially intended as a place of worship for the common, this architectural marvel also serves as a tomb for well-known figures.

9. Leaning Tower of Pisa (from USD 42.0)
It’s not the only leaning bell tower in Italy; there is the bell tower at the church of St. Michele dei Scalzi, and another one at the church of St. Nicola. But the Leaning Tower of Pisa, with its musically-tuned seven bells, is certainly the most famous one. It forms part of a cathedral complex called the Field of Miracles, which features a baptistery, a cemetery, the bell tower, and the cathedral.
Construction of the tower began in 1173, and at that point, the structure began to lean. This was attributed to the soft ground, which began to shift, thus destabilizing the foundation. Construction was completed in 1300s. Over the next 800 years, the Tower of Pisa began to “fall” at a rate of one to two millimeters per year.

The dome was designed by Filippo Brunelleschi in the 15th century.
The Cathedral of Santa Maria del Fiore was constructed where the 7th-century church of Santa Reparata was nestled. Its remains are seen in the crypt. As one of the largest churches in the world, the Cathedral features impressive frescoes. There’s one depicting the Last Judgment, and the other one shows scenes from the Divine Comedy.
