1. Milan Cathedral
Also known as the Duomo di Milano, this grand building is the second largest Catholic cathedral in the world. Only Spain’s Seville Cathedral is larger. The Milan Cathedral is a wondrous white structure that covers an entire block. Its exterior features thousands of spires, and there are more statutes on this gothic and neogothic cathedral than on any other building in the world. Construction on this building first began in 1386, but — probably not surprising given its size — it took approximately five centuries to complete.

2. Cathedral of Monreale
Located in Sicily, this attractive building can be found just a few miles from Palermo, the capital city of this island. The Monreale Cathedral, which was once a part of a royal complex, is considered by many to be the finest example of Norman architecture in Sicily. Construction first began on this building in the 12th century and because Sicilian and Byzantine craftsmen worked on the project, you can see influences from both cultures throughout the cathedral. The Monreale Cathedral is most famous for the gorgeous golden mosaics depicting events from the Bible that cover its interior.

3. Mount Etna
Mount Etna, which is located on Sicily’s east coast, is Europe’s largest and most active volcano. Eruptions, in fact, happen quite frequently. In December 2015, for example, Etna let loose a brief but impressive lava fountain that spewed 3,200 feet over the volcano. Surprisingly, you can still visit this active volcano. There is a cable car that will take you partway up Etna, and from there, you can choose to walk up to designated craters.

4. Trevi Fountain
Even if you didn’t know its name, you are probably familiar with this famous fountain that visitors throw coins in to ensure that they will return to Rome. That fountain is called the Fontana di Trevi or the Trevi Fountain. This stunning beauty is truly a work of art and is the largest Baroque fountain in Rome. The Trevi Fountain consists of a facade and a sea reef created from travertine as well as gorgeous statues carved from Carrara marble.

5. Colosseum

The Colosseum is located in the center of Rome, and it is one of Italy’s most iconic sites. Construction on this impressive building began in 72 AD, and during its heyday, this grand stone amphitheater could seat more than 50,000 spectators and was the site of brutal gladiator battles, chariot races, fights between wild animals as well as humans battling with beasts.
