These intricate trails feature steep staircases with hundreds of stone steps and perilous suspension bridges spanning bottomless chasms. Many remarkable historic buildings are well insulated from the outside world, having served since ancient times to protect their owners from intruders. Beautiful castles and monasteries perch on towering cliffs and rugged mountain terrain, where it’s easy to get lost without a guide. For adventurous travelers, exploring these captivating sites is challenging, as each location holds countless secrets waiting to be discovered.

Castle Bled, Slovenia

One of the most inaccessible structures in the world can be found in Slovenia, where the ancient Bled Castle sits atop 130-meter cliffs. As one of the oldest castles in the country, Bled Castle is nestled in an extraordinarily beautiful area near the lake of the same name. Perched on a rocky outcrop, it hangs dramatically over the lake’s shore and is enveloped by dense forest. Remarkably, this castle was constructed over a thousand years ago, with the first official mention dating back to 1004.

For centuries, the castle has preserved many ancient architectural elements, including the oldest Romanesque tower, which was once used for observing the surrounding area. The castle’s appearance changed significantly during the Middle Ages, as new structures, such as stone towers and defensive walls, were added. The entrance to the castle is concealed within thick woods, accessed via a narrow stone staircase, making it challenging to find without a guide.

Guided tours of the castle grounds offer visitors the chance to learn intriguing stories about its history and explore the interiors of some buildings. A significant portion of the castle houses a historical museum, featuring a rich collection of everyday objects, old clothing, and weaponry. Many tourists are drawn to this remarkable location at sunset, when the ancient castle, perched on its high cliff, is beautifully illuminated as night falls.
