Famous Fortresses and Castles Around the World

Tap a fortress to learn more about it.

The Great Wall of China

A series of fortification walls built across multiple Chinese dynasties over roughly 2,000 years, originally constructed to defend against invasions from northern nomadic groups, and now stretching thousands of kilometers across northern China.

Krak des Chevaliers (Syria)

One of the best-preserved Crusader-era castles in the world, built by the Knights Hospitaller in the 12th century, renowned for its sophisticated concentric defensive design considered highly advanced for its time.

Himeji Castle (Japan)

Often called the "White Heron Castle" for its brilliant white exterior, this is considered Japan's best-preserved original castle and a UNESCO World Heritage Site, having survived both World War II bombing and numerous earthquakes largely intact.

Neuschwanstein Castle (Germany)

A 19th-century Romanesque Revival palace built for King Ludwig II of Bavaria, more a romantic architectural fantasy than a functional defensive fortress, and widely believed to have inspired Disney's iconic castle designs.

The Alhambra (Spain)

A sprawling palace and fortress complex in Granada, built primarily during the Moorish rule of medieval Spain, celebrated for its intricate Islamic architectural detail and elaborate garden courtyards.

Machu Picchu (Peru)

A 15th-century Incan citadel built high in the Andes Mountains, whose exact original purpose remains debated among historians, though it is generally believed to have served as a royal estate rather than a purely military fortress.

Structures built for defense, prestige, or both

While many famous historical fortresses were built primarily for genuine military defense, some, like Neuschwanstein Castle, were constructed centuries later largely as symbolic displays of wealth and power rather than to withstand actual sieges, reflecting how the purpose and meaning of "fortress" architecture evolved considerably over time.

Frequently Asked Questions

Is the Great Wall of China actually visible from space?

This is a widely repeated myth β€” the wall is generally not visible to the naked eye from low Earth orbit under normal conditions, despite persistent popular belief to the contrary, according to multiple astronauts who have specifically looked for it.

Are any of these fortresses still used for their original defensive purpose today?

No β€” all of these sites are now primarily preserved as historical monuments and tourist destinations rather than functioning as active military fortifications, though some remain culturally or symbolically significant to their respective countries.
