Machu Picchu (Peru)

Nestled high in the Andes Mountains, Machu Picchu is a breathtaking 15th-century Inca citadel and UNESCO World Heritage Site. Built as a royal estate for Emperor Pachacuti, it features sophisticated dry-stone architecture, terraced fields, and celestial alignments. Abandoned during the Spanish conquest and hidden for centuries, it was rediscovered in 1911 by Hiram Bingham. Often called the "Lost City of the Incas," its purpose remains debated—serving as a religious, political, or astronomical hub. Today, it stands as one of the New Seven Wonders of the World, attracting millions with its mystical beauty and engineering brilliance.
