When it comes to castles in the sky, many people might think of Hayao Miyazaki’s work. In fact, besides the circular Italian ancient town of Civita di Bagnoregio from that piece, there are many similar castles in the sky around the world. In Japanese author Mizuno Kumi’s book “World’s Castles in the Sky,” as many as 44 castles in the sky scattered across the globe are introduced.
Definition of a Castle in the Sky
In the book “World’s Castles in the Sky,” Mizuno Kumi defines a castle in the sky as a fortress built to showcase dreams, offer prayers, or protect homes, usually constructed on towering and mysterious cliffs or precipices. Moreover, castles in the sky often appear and disappear in the morning mist, sometimes surrounded by sea of clouds. Examples include Japan’s Takeda Castle and Peru’s Machu Picchu. These fortresses, after experiencing the ups and downs of history, still hide many stories behind their mysterious facades.
Based on the definition of a castle in the sky and recommendations from this book as well as backpackers, we have carefully selected six popular and easily accessible European castles in the sky. Let’s take a look together.
Recommended European Castles in the Sky
European Castle in the Sky #1 – Italy’s Civita di Bagnoregio

Of course, the first European castle in the sky we’ll introduce is Italy’s Civita di Bagnoregio, said to be the inspiration for Miyazaki’s animated film “Castle in the Sky.” Built 2,500 years ago, Civita di Bagnoregio is connected to the outside world by only a narrow, long bridge. Surrounded by endless perilous cliffs and wilderness, it looks like an aerial castle from afar, hence earning the name “castle in the sky.”
Visiting this European castle in the sky not only allows you to gaze at the magnificent surrounding scenery but also to experience the tranquility of being cut off from the world. However, because Civita di Bagnoregio is built on steep igneous rock that is eroded by wind day after day, with landslides frequently occurring in the peripheral areas, it is also known as the “dying village.” If you want to go, you’d better seize the opportunity?!

European Castle in the Sky #3 – Mont-Saint-Michel, France

The next European attraction may not be listed in “World’s Castles in the Sky,” but in our opinion, it’s an even more extraordinary castle in the sky. Not only is it built atop towering, precarious cliffs, but it also resembles a heavenly realm above the sea becauseMont-Saint-Michel is surrounded by seawater during high tide, makingthis hilltop town feel like an isolated European village.
Moreover, the Mont-Saint-Michel Abbey took 8 centuries to complete and is the third holiest site in Catholicism. Currently, there are many one-day tour packages designed for tourists. Since many people include Mont-Saint-Michel as a must-visit spot in France, and it’s also been listed as a UNESCO World Heritage Site, its uniqueness is truly worth exploring.
European Castle in the Sky #4 –Segovia Castle

In Kozumi Hisayo’s "The Castles in the Sky Around the World," besides featuring the prototype of "Castle in the Sky," it also includes the inspiration for Disney’s "Snow White" from our childhood — the Alcázar of Segovia, located in the suburbs of Madrid, Spain. Built at the highest point of Segovia, it is recommended to purchase tickets that include access to the top for a breathtaking panoramic view of this European castle in the sky.
The front of the Alcázar of Segovia faces the Segovia Cathedral and city views, while the back is surrounded by endless green countryside. In autumn, the surrounding hills transform into stunning shades of orange and yellow, creating a truly enchanting sight.
After watching the video, you can probably sense just how high the Alcázar of Segovia sits — a perfect match for the definition of a castle in the sky.
Of course — when visiting Segovia, besides seeing the dreamlike castle, you absolutely must not miss the Roman Aqueduct. Built in the 1st century AD, it spans 813 meters in length and stands 30.25 meters tall, consisting of 148 arches across two levels. Its grandeur offers an extraordinary glimpse into Segovia’s rich history and captivating legacy.
#5 of Europe’s Castles in the Sky – Montserrat Monastery in Spain
When talking about Europe’s castles in the sky, we mustn’t forget the world-renowned Montserrat Monastery, located near Barcelona in Spain. Built in the 16th century and reconstructed in 1811 after suffering damage during the Peninsular War, the monastery is a Spanish religious and artistic sanctuary. Its museum houses works by Dalí and Picasso, sculptures by other artists, Europe’s oldest boys' choir, and the Black Madonna.
The reason Montserrat Monastery is called a castle in the sky is due to its location atop jagged, sawtooth-like mountain rocks. The monastery sits 1,236 meters above the valley floor, making it the highest point in the Catalan lowlands. To enjoy the spectacular views, you can take the Montserrat Rack Railway or the cable car up the mountain.,It’s definitely worth a visit.
