Introduction
A personal selection of the world's most extraordinary fortresses – plus the Northumbrian strongholds that started it all…in a web based app.
Growing up in County Durham, castles weren't distant fairy tales — they were simply there, part of the landscape I wandered and was driven around as a bairn. Durham Castle loomed over the river on often mischievous trips into town, its Norman walls hiding university students as easily as they once sheltered prince-bishops. Brancepeth, Raby, Barnard, Lumley — the list goes on, all leaving an indelible mark on the subconscious, maybe?
Those early encounters planted a seed that grew into a lifelong interest. Over the years, I've sought out fortresses across Europe — nine of which I've stood inside (or been in very close proximity to), from the royal splendour of Windsor to the tidal isolation of Mont-Saint-Michel, the fairytale spires of Neuschwanstein to the restored ramparts of Carcassonne. Each left its mark.
This is my curated collection of 21⅓ Castles of Distinction — twenty-one extraordinary strongholds from around the world that I consider the most remarkable (?) for their architecture, history, setting, or sheer atmosphere. The fractional third? Well, that should be obvious from the list! 😉 From a personal perspective, it also represents the pull of the Northumbrian borders — the dramatic coastal castles, inland ruins, and fortified homes that shaped my earliest memories and refuse to be contained in a neat list. (A dedicated map for them is already brewing.)
To bring these places together in one explorable space, I built Castle Explorer — a simple interactive web map where you can filter, sort, and dive into the details. What follows are the stories behind my selection…
The I've Visited List
These are special — not just for their grandeur or history, but because I've stood within (or very close to) their walls or at least viewed from a great vantage point. From local Durham stones that shaped my earliest memories to continental wonders that felt like stepping into legend, each visit deepened the obsession. Here they are in alphabetical order, my brain is too far gone for chronological, sorry!:
Carcassonne
A masterpiece of medieval military architecture, this double-walled fortified city in southern France was originally a Gallo-Roman stronghold. Extensively restored in the 19th century by Eugène Viollet-le-Duc, it's now a UNESCO World Heritage site and one of the best-preserved examples of a walled citadel.
Durham Castle
Built by William the Conqueror's Normans shortly after the Conquest, this motte-and-bailey castle served as the residence of the powerful Prince Bishops of Durham. Today it forms part of Durham University (the oldest university castle in the world) and is a UNESCO site alongside the adjacent cathedral.
Edinburgh Castle
Perched atop an ancient volcanic rock, this iconic fortress has dominated Scotland's capital for centuries. Home to the Scottish Crown Jewels and the Stone of Destiny, it has witnessed sieges, royal births, and the incessant One O'Clock Gun…well done lads!
Ludworth Tower
A classic pele tower built during the turbulent border reiver era for defence against Scottish raids. Now atmospheric ruins in County Durham countryside, it exemplifies the fortified farmhouses common in the Northumbrian borders.
Mont-Saint-Michel
This dramatic tidal island abbey off Normandy's coast began as an 8th-century oratory and grew into a fortified pilgrimage site. Surrounded by quicksands and extreme tides, it's a UNESCO marvel of medieval engineering and spirituality.
Neuschwanstein Castle
King Ludwig II of Bavaria's romantic 19th-century palace, inspired by medieval legends and Wagner operas. Nestled in the Alps, its fairy-tale silhouette inspired Disney's Sleeping Beauty Castle.
Prague Castle
The largest coherent ancient castle complex in the world (Guinness record), overlooking the Vltava River. Seat of Czech kings, Holy Roman Emperors, and presidents, it includes St. Vitus Cathedral and spans Romanesque to Gothic styles.
Tower of London
William the Conqueror's formidable fortress and palace on the Thames, centred on the White Tower. It has served as royal residence, prison, armoury, and treasury — home to the Crown Jewels and infamous executions.
Windsor Castle
The oldest and largest inhabited castle in the world, founded by William the Conqueror. Official residence of the British monarch for over 900 years, with stunning State Apartments and St. George's Chapel.
Buda Castle
Description: Historic palace complex of the Hungarian kings, now housing the Hungarian National Gallery and the Budapest History Museum. Historical Footnote: Heavily damaged in WWII, its reconstruction preserved medieval elements while blending Baroque and modern features.
The Would Be Nice At Some Stage
Pena Palace
A Romanticist palace perched on a hill above Sintra, known for its vivid colours and eclectic architectural styles. Built on the ruins of a monastery destroyed in the 1755 Lisbon earthquake, it represents the peak of 19th-century Romantic revivalism in Europe.
Matsumoto Castle
Nicknamed 'Crow Castle' for its dramatic black-and-white exterior, this elegant feudal keep is one of Japan's oldest surviving original castles, surrounded by a moat and cherry blossoms in spring. Built during the Sengoku (Warring States) period, it survived earthquakes and wars intact—earning National Treasure status as one of only five original castle keeps left in Japan.
Kremlin (Moscow)
The fortified complex at the heart of Moscow, housing the Russian president and iconic cathedrals. It has been the seat of Russian power for centuries, surviving Mongol invasions, fires, and revolutions to remain a symbol of state authority.
Krak des Chevaliers
One of the best-preserved Crusader castles, perched on a hill overlooking the Homs Gap. Its massive walls and towers dominate the landscape. It withstood numerous sieges during the Crusades and was described by a 13th-century visitor as the 'strongest castle in the world.' Richard The Lionheart's favourite B&B!
Himeji Castle
Japan's most spectacular surviving feudal castle, known as the White Heron due to its brilliant white exterior. It is a UNESCO World Heritage Site. Historical Footnote: One of only a handful of original Japanese castles to survive intact into the modern era, it narrowly escaped destruction in WWII bombings.
Chateau de Versailles
The opulent Baroque masterpiece and former residence of French kings Louis XIV to Louis XVI, famed for its Hall of Mirrors, vast gardens, and fountains. Symbol of absolute monarchy and excess that fuelled the French Revolution. Louis XIV moved the court here in 1661 to control nobles—leading to the famous 'Sun King' era, but also the 1789 Revolution when the palace was stormed.
Chateau de Chenonceau
Spanning the River Cher, this elegant Renaissance château is famed for its graceful arches and beautiful gardens. It played a role in both the Hundred Years' War and World War II. During WWII, the gallery over the river served as an escape route from occupied to free France.
Bran Castle
Often marketed as Dracula's Castle, this medieval fortress sits atop a cliff in Transylvania. It now houses a museum of art and furniture. While not actually Vlad the Impaler's residence, its eerie location and 20th-century marketing tied it forever to Bram Stoker's Dracula legend.
Bodiam Castle
A quintessential moated medieval castle built by Sir Edward Dalyngrigge to defend against French invasion. Never seriously attacked in its prime, it fell into ruin after the English Civil War but was restored in the 20th century as a romantic ruin.
Alhambra
A sprawling palace-fortress complex in Granada, showcasing exquisite Moorish architecture, intricate tilework, and lush gardens. The last Muslim stronghold in Spain fell here in 1492, marking the end of nearly 800 years of Islamic rule on the Iberian Peninsula.
Alcazar of Segovia
Perched dramatically on a rocky crag like a ship's bow, this fairy-tale fortress, another that inspired Disney's Cinderella Castle with its pointed turrets and moat. Once a royal residence for Castilian kings. Isabella I was crowned Queen of Castile here in 1474—launching the era that unified Spain and funded Columbus's voyages.
In Closing: Why Castles Still Matter
Castles, for me, aren't just stone and history — they're markers of lives lived boldly: places of refuge, power, romance, and ruin. From the everyday Northumbrian strongholds that shaped my appreciation to the continental wonders that felt like stepping into legend, these massive feats of human ingenuity have stayed with me for a reason. They remind us that the past isn't distant; it's hidden in plain sight, waiting for a curious glance or an accidental detour.
That's why I built Castle Explorer — a simple, interactive web map to share these places with anyone who feels the same pull. No frameworks, just vanilla JavaScript and Leaflet, running (smoothly?) on anything from a phone (while standing outside a real castle) to a desktop.
A huge thank you to the wonderful open-source community — Leaflet.js, OpenStreetMap contributors, and countless tools that made this project possible without reinventing the wheel. The app is fully open-source (MIT licensed), so if a castle speaks to you (especially a Northumbrian one), fork the repo, add it to castles.json, and off ye go with your own version.
Thanks for reading — what's your favourite castle?
