Commissioned by Ludwig II of Bavaria in 1869, it was intended as a personal refuge for the reclusive king but has since become one of the most popular tourist destinations in Europe. Its turrets and towers reach towards the sky, embodying the romantic ideals of the Middle Ages. Inside, the rooms are adorned with murals depicting scenes from Richard Wagner's operas, reflecting Ludwig's love for the composer.

2. Château de Chambord, France: A testament to the grandeur of the French Renaissance, the Château de Chambord is known for its distinctive French Gothic architecture. It features an intricate roofscape that mirrors a city skyline, complete with 11 kinds of towers and three types of chimneys. The chateau boasts a unique double helix staircase, believed to be influenced by Leonardo da Vinci. Built as a hunting lodge for King Francis I in the 16th century, it stands as a symbol of royal power and architectural innovation.

3. Himeji Castle, Japan: Known as "White Heron Castle" due to its brilliant white exterior and elegant shape, Himeji Castle is a masterpiece of Japanese feudal period architecture. Constructed in the 14th century, it is one of the oldest surviving structures from medieval Japan. Its complex defensive design, including a maze-like approach meant to confuse invaders, showcases the strategic ingenuity of the era.
