Medieval Fortress Legends
The Origins of an Iconic Stronghold
To begin with, the Caetani Castle of Sermoneta dates back to the 13th century, when it was originally constructed by the Annibaldi family. This early complex was dominated by two core defensive structures: the imposing “Maschio” tower and the smaller “Maschietto”, which together defined the first phase of the fortress.
As the centuries passed, Medieval Fortress Legends continued to grow around these towers, thanks to battles, noble intrigues, and papal politics.
A Castle Reinvented by the Caetani
Transitioning into Power
In 1297, the Annibaldi lost control of Sermoneta, and the entire territory was granted to the Caetani, one of the most influential Roman families. Consequently, they transformed the stronghold into an architectural and political powerhouse.
A Residence as Well as a Fortress
The Caetani expanded the castle with new residential wings, audience halls, and defensive improvements. Furthermore, they enriched its interiors with art and ornamentation. Among the most remarkable additions were the “Camere Pinte” (Painted Rooms), adorned with Renaissance frescoes attributed to an artist close to Pinturicchio.

Artistic Treasures and Architectural Marvels
The Painted Rooms
Inside these extraordinary chambers, visitors will find vivid scenes—mythological, allegorical, and perhaps even political—testifying to the refined cultural environment cultivated by the Caetani family.
The Hall of the Barons
Moreover, the castle houses the monumental Sala dei Baroni, a 22-meter-long hall used for meetings, ceremonies, and feudal gatherings. Its stone arches, acoustics, and solemn atmosphere make it one of the most iconic rooms in the entire complex.
Defensive Features
In addition, the castle preserves:
- the large Piazza d’Armi (the main military courtyard)
- ancient prisons
- ramparts and guard walks
- the Borgia residence, added during the brief takeover by Pope Alexander VI
Each element strengthens the timeless aura of Medieval Fortress Legends that surrounds the entire site.
Centuries of Turmoil: Caetani, Borgia, and Napoleon
Political Upheaval
During the late 1400s, the Borgia family seized the castle, fortifying it even further. They added new prisons, stronger walls, and military structures. Their changes erased several Caetani symbols, including parts of their family chapel.
Restoration and Decline
After the fall of the Borgia, the Caetani regained ownership in 1504. However, over time the strategic importance of the Pontine Plain faded, and the castle began a slow decline. Later on, Napoleonic troops damaged and looted it during their movements through the region.
Modern Renaissance
Fortunately, in the late 19th century the Caetani family restored the complex. Today, the castle — managed by the Roffredo Caetani Foundation — hosts cultural events, guided tours, studies in art restoration, and historical exhibitions.
