1. Malbork Castle 🇵🇱

Malbork Castle (Castle of the Teutonic Order) in Poland is the largest castle in the world at 143,591 m². Built beginning in 1274 by the Teutonic Knights, this massive Gothic fortress served as the headquarters of the Order for nearly 150 years. It is also the largest brick building ever constructed.

The castle consists of three main sections: the High Castle (the Order’s monastery), the Middle Castle (administrative center), and the Low Castle (armory and workshops). Nearly destroyed during World War II, it was painstakingly restored over decades and became a UNESCO World Heritage Site in 1997. Today, it houses a museum and attracts nearly 500,000 visitors annually.

2. Mehrangarh Fort 🇮🇳

Mehrangarh Fort in Jodhpur, India, covers approximately 81,000 m² and rises 125 meters above the Blue City on a perpendicular cliff. Founded in 1459 by Rao Jodha, the fort is one of the largest and most spectacular in India.

The fort’s towering walls (up to 36 meters high and 21 meters thick in places) contain a series of palaces, courtyards, and museums with an outstanding collection of Rajput artifacts. The fort featured in the Christopher Nolan film The Dark Knight Rises (2012) and is considered one of the best-preserved forts in India.

3. Prague Castle 🇨🇿

Prague Castle, recognized by the Guinness World Records as the largest ancient castle complex, covers 70,000 m² in the heart of Prague, Czech Republic. Dating to around 870 AD, it has served as the seat of Czech rulers — kings, emperors, and presidents — for over 1,100 years.

The complex includes St. Vitus Cathedral (which took nearly 600 years to complete), the Old Royal Palace, Golden Lane, and extensive gardens. It remains the official residence of the Czech president and is the most visited tourist attraction in Prague, welcoming nearly 2 million visitors per year.

4. Windsor Castle 🏴󠁧󠁢󠁥󠁮󠁧󠁿

Windsor Castle in England spans 55,000 m² and is the oldest and largest occupied castle in the world. William the Conqueror chose the site after the Norman Conquest of 1066, and British monarchs have continuously lived here for nearly 1,000 years. It is one of three official residences of the current British monarch.

The castle survived a devastating fire in 1992 that destroyed 115 rooms, requiring a five-year restoration at a cost of £36.5 million. Queen Elizabeth II made Windsor her primary residence during the COVID-19 pandemic, and she passed away there in 2022.

5–7. Buda Castle, Spiš Castle, and the Citadel of Aleppo

Buda Castle (44,674 m²) crowns Castle Hill in Budapest, Hungary, and now houses the Hungarian National Gallery and Budapest History Museum. Spiš Castle (41,426 m²) in Slovakia is one of the largest castle ruins in Central Europe. The Citadel of Aleppo (39,804 m²) in Syria is one of the oldest castles in the world — occupation of the hill dates to at least the 3rd millennium BC. Tragically, it sustained significant damage during the Syrian Civil War.

8–10. Edinburgh, Hohensalzburg, and Chambord

Edinburgh Castle (35,737 m²) dominates the Scottish capital from Castle Rock and is Scotland’s most visited paid attraction. Hohensalzburg Fortress (30,000 m²) in Salzburg, Austria, is one of the largest medieval castles in Europe and accessible by funicular railway. Château de Chambord (28,000 m²) in France’s Loire Valley was built by King Francis I as a hunting lodge — it features 440 rooms, 365 fireplaces, and 84 staircases, including a famous double-helix staircase attributed to Leonardo da Vinci.

11–15. From Japan to Wales

Himeji Castle (23,300 m²) in Japan is the finest surviving example of Japanese castle architecture and a UNESCO World Heritage Site known as the “White Heron Castle.” Alnwick Castle (22,000 m²) in England served as Hogwarts in the first two Harry Potter films. Warwick Castle (20,800 m²) has been converted into a theme park by Merlin Entertainments. Bran Castle (20,500 m²) in Romania is marketed as “Dracula’s Castle,” though its connection to Vlad the Impaler is tenuous. Conwy Castle (19,500 m²) in Wales is a masterpiece of medieval military architecture, part of the UNESCO-listed Castles and Town Walls of King Edward I.
