Top 10 Italian Castles in 2026

Castel Sant'Angelo’s cylindrical silhouette dominates Rome’s skyline, a 1,900-year evolution from Emperor Hadrian’s mausoleum to a papal fortress and prison. This layered history spans 1,900 years, longer than any other castle on this list—outlasting #1’s 800-year-old octagonal design by more than a millennium. The castle’s 58-meter diameter and 21-meter-thick walls reflect its military adaptation, while the Passetto di Borgo passage connects it to the Vatican, a 0.8-kilometer escape route used during the 1527 Sack of Rome. It houses over 200,000 artifacts in its national museum, showcasing art from antiquity to the Renaissance.

Castello Sforzesco is Milan’s formidable 15th-century fortress, housing Michelangelo’s last sculpture, the Rondanini Pietà, and Leonardo da Vinci’s iconic ceiling frescoes in the Sala delle Asse. Spanning over 500 years of history, its art collection surpasses #4’s medieval frescoes in both Renaissance pedigree and scale, with masterpieces spanning three centuries. The castle’s 70,000-square-meter grounds enclose seven museums, including the Museo d’Arte Antica with 1,500 pieces. Its defensive walls stretch 1.2 kilometers, and the Torre del Filarete stands at 70 meters tall, a symbol of Sforza power that rivals #2’s Roman origins in political significance.

Castello di Fénis rises like a storybook vision in the Aosta Valley, its crenellated towers and double encircling walls fully intact since the 14th century. The castle’s 500 square meters of frescoes, including the famed Judgment of Solomon cycle, depict courtly life with vivid detail. Located at 1,200 meters altitude, it commands alpine views that no other castle on this list can match—while #3’s Milanese fortress sits at just 122 meters above sea level. Its drawbridge and 30-meter-high keep remain functional, offering a tangible link to 1342, when the Challant family completed the structure. A rare example of medieval military architecture preserved without later modifications.

Rocca Scaligera is the only lakeside fortress in Italy with a functional medieval dock, rising 30 meters directly from Lake Garda. Built in 1277, its massive walls and tower remain intact, drawing over 400,000 visitors annually. Its dock, carved from original 13th-century stone, allowed discreet boat access for supplies and escapes—a feature no other Italian castle retains. This dock outperforms #6 Castello Aragonese, Ischia's modern bridge in historical authenticity, as the latter was rebuilt in the 19th century.

Castello Aragonese, Ischia, is the oldest continuously inhabited fortress in Italy, with origins dating to 474 BC. Perched on a volcanic rock islet, it connects to the mainland via a 220-meter stone bridge built in the 15th century. The site encompasses a cathedral and 200 rooms, with a recorded 150,000 tourists exploring its tunnels annually. This ancient settlement predates every other castle on this list by over 1,500 years, making it historically richer than #5 Rocca Scaligera, Sirmione's 13th-century structure.

Castello di Sammezzano boasts the most extravagant Moorish-revival interiors in Italy, with over 365 kaleidoscopic rooms rivaling the Alhambra's intricacy. Abandoned since the 1970s, its patterned ceilings and 24,000 individually painted tiles remain largely untouched. Despite no official visitor count, restoration estimates exceed €10 million. Its architectural wealth surpasses #8 Forte di Bard's military austerity, offering a dreamlike experience that few castles on this list can match.

Forte di Bard is the best-preserved 19th-century Alpine fortress in Italy, restored over 20 years at a cost of €30 million. Its three-tiered structure features 283 rooms and a 90-meter deep well, now housing multiple museums. Appearing as HYDRA's base in the Avengers films, it draws 250,000 visitors yearly. This cinematic fame gives it a pop-culture edge over #7 Castello di Sammezzano, Tuscany's obscure splendor, while its defensive architecture offers a stark contrast to Rocca Scaligera's lakeside elegance.

Ferrara’s only completely moated castle, Castello Estense, remains the city’s architectural heart. Its four massive towers, each 30 meters tall, enclose a courtyard that has hosted Este dukes for over 600 years. The castle’s brick walls, completed in 1440, survived multiple earthquakes and sieges. While Castel Nuovo (#10) boasts a Renaissance triumphal arch, Castello Estense preserves an earlier, unbroken medieval layout – its original drawbridge still spans the 12-meter-wide moat.

Castel Nuovo, also known as Maschio Angioino, dominates Naples’ waterfront with its iconic 15th-century triumphal arch. Construction began in 1279 under Charles I of Anjou, but the marble arch, sculpted by Francesco Laurana, was added in 1467. The castle’s five cylindrical towers each rise 25 meters, and the main hall hosts the municipal museum with over 1,000 artifacts. Unlike the fully moated Castello Estense, Castel Nuovo’s defensive ditch has long been filled, but its waterfront position remains equally strategic.
