Abandoned Castles and Fortresses That Look Straight Out of a Fairy Tale

12. Castel del Monte: An Architectural Enigma

Unlike any other fortress in Europe, Castel del Monte is a masterpiece of mathematical and symbolic precision. Built in the 13th century by Emperor Frederick II in the Apulia region of Italy, its perfect octagonal shape and eight equally spaced towers have puzzled historians for centuries. Was it a hunting lodge, a military stronghold, or an astronomical observatory? No one knows for sure. Unlike typical medieval castles, it lacks a moat, defensive walls, or clear military purpose, adding to its mystique. The golden limestone façade and geometric symmetry make Castel del Monte an architectural marvel that continues to intrigue scholars and captivate visitors. Whether exploring its precisely constructed interiors or admiring its strategic hilltop views, travelers are left with a lingering question—what was Emperor Frederick’s true vision for this enigmatic masterpiece?
