Naples, a city steeped in history and culture, conceals stories of power, intrigue, and betrayal within its ancient streets. In the 15th century, under the rule of the Aragonese dynasty, the city was the stage for a crucial event: the Barons’ Conspiracy. This episode of rebellion against King Ferrante I has left an indelible mark on Neapolitan history, and today, we invite you to retrace its steps through a suggestive walking itinerary that will lead you to the symbolic places of that dramatic affair.
Castel Nuovo: Heart of Power and Intrigue
Our journey begins at the imposing Castel Nuovo, also known as Maschio Angioino, a true emblem of Neapolitan power. Its origins date back to the 13th century, when Charles I of Anjou decided to build a new royal residence near the port. However, it was in the 15th century, under the Aragonese dynasty, that the castle underwent important transformations. Alfonso V of Aragon renovated it extensively, transforming it into an even more imposing fortress, suitable for the military needs of the time. The five majestic cylindrical towers and the famous Triumphal Arch, a Renaissance masterpiece celebrating Alfonso V’s entrance into Naples in 1443, testify to the greatness of this era.
It was in this context of power that the figure of King Ferrante I, son of Alfonso V, emerged. Eager to consolidate the crown’s power, Ferrante I pursued a policy aimed at weakening feudal ties and centralizing authority. These reforms aroused the discontent of the powerful Neapolitan barons, who saw their privileges and influence threatened. Already in 1462, a first revolt had occurred, promptly suppressed by the king, but tensions simmered beneath the surface, ready to explode in a new and more dramatic attempt at rebellion. The heavy taxes imposed by the sovereign and the fear of losing their possessions around Naples further sharpened the nobility’s resentment, creating fertile ground for conspiracy.
The Infamous Hall of Barons
Inside Castel Nuovo, our attention focuses on the Hall of Barons, originally known as the Great Hall or Throne Room. This imposing space became infamously known for the epilogue of the Barons’ Conspiracy. In 1486 (or 1487 according to some sources), King Ferrante I, with cunning, invited the conspiring barons to a banquet, under the pretext of celebrating his niece’s wedding. The sumptuous hall, designed by Majorcan architect Guillermo Sagrera, with its cubic shape and the splendid octagonal ribbed vault open at the center by an oculus, was the theater of an act of betrayal. Once the barons were gathered, the king had the doors closed and had them arrested. It is said, although not confirmed by all sources, that archers hidden in the windows of the hall were ready to intervene. This event marked the end of the conspiracy and the consolidation of Ferrante I’s power. The hall, despite having suffered damage from a fire in 1919 that caused the loss of some original sculptures by Pere Johan, still retains its historic charm and today hosts the meetings of the Naples City Council. The Hall of Barons is generally accessible to the public as part of the museum tour of Castel Nuovo, but it is advisable to check its availability in advance.
Into the Darkness: The Prisons of Castel Nuovo
Our path continues in the underground areas of Castel Nuovo, specifically in the area beneath the Palatine Chapel, where the ancient prisons were located. The most famous is the “Fossa del Miglio” (Millet Pit), better known as the “Crocodile Pit.” Originally used as a grain storage during the Aragonese reign, it was later converted into a prison for those condemned to more severe punishments. A legend tells of a crocodile that, entering the pit through an opening, dragged prisoners into the sea. There are also other versions of this macabre story, one of which involves Queen Joanna II. Next to the Millet Pit is the “Prison of the Barons’ Conspiracy” or “Barons’ Pit,” where it is said the remains of some of the nobles who participated in the conspiracy of 1485 (or 1486) are preserved in four unmarked coffins. Other areas of the castle, such as the underground areas of the Gold Tower, the Guard Tower, and the St. George Tower, were occasionally used as prisons. The Millet Pit and the Barons’ Prison are generally accessible to visitors, offering an eerie glimpse into the castle’s past.
Piazza Mercato: Where Justice Was Executed
Leaving Castel Nuovo, we head toward Piazza Mercato, a place of great historical importance located southeast of the castle. In the 15th century, this was the city’s main market square and an important center for public events, including executions. Originally called Piazza del Moricino, it was the scene of numerous capital executions. Although sources do not specify whether the conspiring barons were executed here (some were probably executed inside Castel Nuovo), Piazza Mercato was the official site for state executions at the time. A significant event that marked the history of this square was indeed the execution of Conradin of Swabia in 1268, which established this place as a site for capital sentences. The revolt of Masaniello in the 17th century also had its epicenter in this square. Today, Piazza Mercato retains its commercial and social vibrancy, surrounded by historic churches such as the Church of Santa Croce and Purgatorio al Mercato and the Church of Santa Maria del Carmine.
On the Traces of the Citadel and Petrucci’s Fate
Your research might lead you on the trail of Naples’ “citadel” in the 15th century. However, sources do not mention a “citadel” distinct from Castel Nuovo in that period. It is likely that the term refers to the fortified area of the castle itself, which served as the city’s main stronghold and royal residence. Among the main architects of the Barons’ Conspiracy was Antonello Petrucci. Although sources do not specify the exact location of his execution, it is very likely that, like many other barons involved, he met his death inside Castel Nuovo or in an area strictly controlled by royal power. The castle, at the heart of the conspiracy’s repression, was the scene of torture and death for many of the rebels.
