Italy is often associated with Renaissance art, ancient Roman ruins, and picturesque coastal villages, but one of its most awe-inspiring and often overlooked treasures lies in its staggering collection of castles. With an estimated 25,000 castles, fortresses, towers, and fortified residences, Italy holds one of the richest medieval heritages in Europe.
From soaring citadels in the snow-capped Alps to mysterious Norman towers in the Sicilian countryside, these castles are living monuments to the shifting tides of war, power, love, and art that shaped Italy over the centuries.
Whether you’re a passionate historian, an architecture lover, or an armchair traveler looking for inspiration, Italy’s castles offer an unforgettable journey through time.
Why Are There So Many Castles in Italy?
The sheer number of castles in Italy stems from its fragmented medieval history. Unlike countries unified under a single monarchy, Italy remained divided into city-states, duchies, kingdoms, and religious territories for centuries.
Each power center needed to defend its lands, assert its wealth, and control trade routes or mountain passes. As a result, castles were built not only by emperors and kings, but also by noble families, bishops, mercenary lords, and even townspeople. Many Italian castles were rebuilt, expanded, or reused across the centuries, from Roman fortresses to Renaissance villas.
Northern Italy: From Alpine Guardians to Renaissance Courts
Castel Beseno (Trentino-Alto Adige)
Perched on a ridge above the Adige Valley, Castel Beseno is the largest castle in Trentino and a true guardian of the north. Rebuilt in the 16th century, it served as a fortress during the Battle of Calliano (1487) and now hosts medieval reenactments and panoramic tours.
Castello Sforzesco (Milan)
One of the grandest urban castles in Italy, the Sforza Castle was transformed from fortress to ducal residence by the mighty Sforza family in the 15th century. It boasts contributions from Leonardo da Vinci, Michelangelo’s Pietà Rondanini, and several museums under its vast roof.
Castel Thun (Trentino)
A lesser-known gem, this castle in Val di Non is beautifully preserved and rich in noble history. Owned by the Thun family from the 13th century to the 20th, it features original furnishings, wooden coffered ceilings, and an extensive library.
Central Italy: Strongholds of Nobility, Papal Power, and Romantic Escapes
Castello di Torrechiara (Emilia-Romagna)
Built by Count Pier Maria Rossi for his beloved Bianca Pellegrini, Torrechiara Castle is a romantic Renaissance treasure. Its Camera d’Oro is a glorious tribute to courtly love, while the surrounding hills produce some of Parma’s finest wines.
Castel Sant’Angelo (Rome)
Originally Emperor Hadrian’s mausoleum, it evolved into a papal fortress, refuge, and prison. With its towering ramparts, angel-topped dome, and hidden passageway to the Vatican, Castel Sant’Angelo is steeped in power, legend, and ecclesiastical drama.
Rocca di Gradara (Le Marche)
Famous for the doomed love story of Paolo and Francesca, immortalized by Dante in The Divine Comedy, Gradara Castle sits above the Adriatic coast. It’s one of Italy’s best-preserved fortresses, complete with drawbridge, watchtowers, and immersive medieval festivals.
Southern Italy: From Norman Fortresses to Esoteric Palaces
Castel del Monte (Puglia)
No list would be complete without Frederick II’s geometric masterpiece. This octagonal, mathematically precise castle defies categorization: it was not clearly military or residential. A UNESCO World Heritage Site, it fuses Gothic, Classical, Islamic, and astronomical elements into a truly unique monument.
Castello Aragonese (Ischia)
This island fortress near Naples rises dramatically from a volcanic rock. Built in 474 BC and expanded by the Aragonese in the 15th century, it once housed churches, convents, prisons, and even vineyards. Today, it’s a romantic location for weddings and tours.
Castello Normanno-Svevo (Bari)
Built by the Normans and expanded by Emperor Frederick II, this sea-facing fortress stood guard against Saracen attacks. With its massive stone walls and moat, it remains one of southern Italy’s most imposing castles.
Sicily & Sardinia: Island Strongholds and Noble Ruins
Castello Ursino (Catania, Sicily)
Originally a coastal castle built by Frederick II in the 13th century, it now stands inland, surrounded by lava from Mount Etna’s eruptions. Today, it hosts Catania’s civic museum and remains a symbol of Sicilian resilience.
Castello di Lombardia (Enna, Sicily)
One of Italy’s largest and highest castles, it sits atop the town of Enna, offering sweeping views over central Sicily. Once a stronghold for Greeks, Romans, Byzantines, Arabs, and Normans, it boasts multiple towers and vast open courtyards.
Castello di Acquafredda (Sardinia)
Built on a volcanic hill near Cagliari, this Sardinian fortress is a scenic ruin reached by hiking trail. Though in partial collapse, it retains its mystical atmosphere and panoramic views across the Campidano plain.
Haunted Castles and Legendary Tales
Italy’s castles are often steeped in folklore and ghost stories, many of which have endured for centuries.
Castello di Bardi (Emilia-Romagna): Said to be haunted by the spirit of Moroello, a knight who died in a tragic love affair.
Castello di Montebello (Emilia-Romagna): Known for the legend of Azzurrina, a little girl with albinism who vanished in the dungeons.

These castles attract ghost hunters, romantics, and skeptics alike, adding a chilling layer to their history.
