It is actually a working aqueduct that was built by the Romans in the 1st century A.D. and still supplies the region with 44 million gallons of water each day. The engineering design of this bridge is a marvel because each stone was precisely hand laid, built without mortar and has a gradient of less than 1 inch per 500 yards

5. Burj Khalifa, Dubai, UAE

Burj Khalifa in Dubai takes home the title as the world’s tallest building at 2,723 feet tall and 160 stories.

The 5,000-year-old megalithic circle continues to fascinate because the Britons who built it left no written record. Was it built as a holy site or was it a scientific observatory? Was it built by Merlin of Arthurian lore or did UFO’s use it as a landing site?
