This is one of the few surviving parts of the ancient defence system that once surrounded the Old Town. Built in the early 14th century, it was the main defence of the north. Further towers were added in the 15th century, but the Florian's Gate is the only remaining gate from the original eight. In 1660, it was extended to include a Baroque roof, raising its height by one metre, and today it measures around 33.5 metres.

The Florida Aquarium is a large scale 250,000 square-foot facility.

Located next to the Church of Suffragio in Piazza Ferrari, the City Museum, Museo Della Città, is housed within a former Jesuit monastery. It has numerous exhibits of local historical and artistic heritage including those in the Roman Lapidary, the Archaeological Section and paintings.

This 14th-century church, known as Santuario della Madonna della Misericordia in Italian, is renowned for the portrait of Madonna della Misericordia, painted by the artist Giuseppe Soleri in the 18th–19th century. Located near the Augustus Arch, this sanctuary was originally constructed by Clarisse nuns. Throughout its history, this church has been a site of continuous pilgrimages and a place of profound prayer. It is said that the miraculous image of Madonna della Misericordia moved its eyes in 1850, adding to its mystique. As a result, the 12th of every month holds special significance as a day to commemorate this miraculous event.
