7 most beautiful castles in the world you should visit at least once

There’s something about castles that tugs at the imagination. Maybe it’s the hint of romance in their towers, or the way they instantly pull us into stories of knights in shining armour and queens who ruled with quiet strength.

A true castle has always been both home and fortress, a place built to protect, but also to impress. And while we often think of them as a purely European idea, this architectural style stretches far wider, appearing in places as unexpected as Japan, India, Morocco and even Mexico.

Today, many of these ancient strongholds have become living museums, where visitors can watch jousts, hear medieval music or see artisans practise centuries-old skills. Together, they remind us that history isn’t just something we read, it’s something we can walk through, tower by tower.

This medieval fortress rises above the island of Rhodes in the Aegean Sea. It began as a Byzantine citadel before the Knights of St. John rebuilt it in a grand Gothic style when their leader, the grand master, ruled from here. During Italy’s brief control of the Dodecanese Islands, Benito Mussolini even used the castle as a holiday retreat. Today, its permanent archaeological displays showcase artefacts from ancient Greece and the early Christian era.

Kalmar Castle traces its origins to the closing years of the Viking Age, beginning as a 12th-century defensive tower overlooking the Kalmar Strait on the Baltic Sea. Nearly four centuries later, King Gustav and his sons transformed it into a Renaissance-style royal residence. Careful restoration has preserved its 1592 appearance remarkably well. Today, the castle offers exhibitions, guided tours, and activities for children, and also hosts special events, including an ongoing ancient Egyptian artefact exhibition running until November 2025.

Built in the early 17th century by the Mughal-influenced rulers of Rajasthan, Amber Fort rises dramatically on a hill overlooking Jaipur, its reflection shimmering in the Maota Lake below. The sprawling complex opens into grand courtyards framed by elegant Rajput-style structures such as the Maharaja’s Apartments, Sukh Niwas (the Hall of Pleasure), and the Diwan-i-Am (Hall of Public Audience). Although elephants once carried visitors up the steep approach, most travellers today either walk or use a 4x4 vehicle to reach the fort.

Guarding the entrance to San Juan Bay, this 16th-century Spanish stronghold is one of the Caribbean’s most striking landmarks. It’s protected by cliffs, a moat with a drawbridge and thick stone walls. Over the centuries, it survived attacks from pirates, French forces and even Sir Francis Drake in 1595. It finally fell to the US after heavy naval fire during the Spanish-American War. Since 1962, El Morro and nearby Castillo San Cristóbal have formed the San Juan National Historic Site, where the wide lawn in front is now a favourite spot for picnics and kite flying.

Set high on an ancient volcanic rock at the end of the Royal Mile, Edinburgh Castle is often called the most besieged place in Britain, having endured more than 26 major attacks in over 1,100 years. Figures like Mary Queen of Scots, Oliver Cromwell and Sir Walter Raleigh are closely tied to its history. The castle houses the Honours of Scotland, the country’s oldest crown jewels, and provides a dramatic setting for the annual Royal Edinburgh Military Tattoo. Throughout the year, visitors can enjoy concerts, historical demonstrations and even visit the unique Dog Cemetery, where former military mascots are laid to rest.

Chambord is one of the best examples of the shift from fortified medieval castles to grand Renaissance residences. Built in the early 16th century as King François I’s “hunting lodge,” the enormous chateau, with 440 rooms, took 28 years to finish. Its moat and towers are mostly decorative, but the castle is home to genuine marvels, including its famous double helix staircase, believed to be inspired by Leonardo da Vinci.

Shuri Castle is a standout example of Chinese-influenced architecture in Japan. Perched on a hill in Okinawa, it served as the palace complex of the Ryukyu Kingdom for over 450 years, during a time when the islands had close cultural ties with China. Its grounds included royal living quarters, audience halls, shrines and a lavish throne room that resembled the Forbidden City. Much of Shuri was rebuilt after World War II, when it was used as a military base. Today, visitors can watch the morning Ukejo gate-opening ceremony, explore with multilingual audio guides, enjoy traditional dance shows and see the castle beautifully illuminated at night.

Whether you’re drawn to fairytale turrets or soaring stone fortresses, these castles are more than just relics of the past, they’re windows into history, culture, and timeless beauty. Visiting them is a journey into stories that still echo today.
