If you're tight on time, this Naples city tour is for you. You'll explore the city in an air-conditioned coach and pay a visit to some of Naples's most famous landmarks.

Have your camera ready to snap photos; one of your first stops is the Naples Cathedral, the city's main church. There, you'll have the opportunity to see the Royal Chapel of the Treasure of San Gennaro, known for its assortment of frescoes by notable 17th-century artists like Fabrizio Santafede.

The Naples city bus tour continues to New Castle, a medieval castle with a storied past. Construction on the castle began in 1279 when it was ordered by Charles I of Anjou to house his court. The castle is mainly known for its impressive arch, a single-sided white marble arch that is 35 meters tall; its Renaissance style is highly regarded by architects worldwide. Then stop at Posillipo for a panoramic photo opportunity on the St. Antonio church terrace for the best view of the city and the bay.

End your tour at Plebiscite Square to admire the front of the Royal Palace. This structure was once a residence of the Bourbon Kings, a European royal house of French origin. The house contains various statues of former kings of Naples, but strangely none of the statues make mention of the Bourbon dynasty.
