1. Pompeii Archaeological Site (from USD 55.8)
Pompeii Archaeological Site, nestled beneath the shadow of Mount Vesuvius near Naples, is an enchanting time capsule of ancient Roman life. Its fame arises from a remarkable history that was, quite literally, buried and preserved for centuries. In 79 AD, a cataclysmic eruption of Mount Vesuvius unleashed a torrent of volcanic ash and pumice, smothering the thriving city of Pompeii and its inhabitants.
This natural disaster, while devastating, inadvertently safeguarded the city, allowing modern-day archaeologists to unveil an astonishing glimpse into the daily routines, artistry, and architecture of an ancient Roman society. As you wander through its labyrinthine streets, marvel at the vivid frescoes that once adorned private homes and stand in the perfectly preserved amphitheater, where you’ll be transported back in time.

2. Castel Sant'Angelo (from USD 14.63)
Originally constructed as a mausoleum for Roman emperor Hadrian in the 2nd century AD, Castel Sant'Angelo housed the remains of the emperor and his successors. This towering cylindrical structure, adorned with impressive sculptures, reflects a fusion of Roman and medieval architectural styles. Over time, it transformed into a fortress, a papal refuge, and a prison. Its name derives from vision that Pope Gregory the Great had in 590 AD of Archangel Michael atop the castle.
It served as a sanctuary for popes during times of turmoil, connected to the Vatican by Passetto di Borgo. Today, it stands as a museum preserving the rich tapestry of its past, housing historical artifacts, and providing panoramic vistas of Rome from its terraces.

3. Colosseum (from USD 70.44)
At 188 meters (617 ft) in length, 156 meters (512 ft) in width, and 57 meters (187 ft) in height, the Colosseum is one of the most impressive buildings in Italy. 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.

One of the largest Catholic churches in the world, the Duomo di Milano can accommodate 40,000 people.

Both wanted a spectacular building, which they certainly accomplished. The Duomo di Milano is one of the more decadent churches in the world, with 700 figures, 3,400 statues, and an abundance of gargoyles. A good time to visit would be on a Monday after vespers because that’s when one of the nails used in the crucifixion of Jesus is exhibited.

There are 414 steps, and no elevators. So, those who have heart problems, claustrophobia, and vertigo are advised against climbing the Giotto’s.
In the tower’s many niches, you’ll find 16 life-size statues. These have been made by different artists, which includes Donatello. But, these statues are only copies; the real things are on display at the Museo dell’Opera del Duomo.

9. Leaning Tower of Pisa (from USD 38.0)
This famous place in Italy doesn’t need an introduction. The Leaning Tower of Pisa is 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 the 1300s. Over the next 800 years, the Tower of Pisa began to “fall” at a rate of one to two millimeters per year.
