The Great Pyramid of Giza was the tallest structure in the world for over 3,800 years.#FunFactFriday 
It is said to have been constructed from over 2,300,000 blocks of limestone, although no one can agree on whether the workers dragged, lifted, or rolled them into place. Adjusted for modern costs, at $496 per block plus labor and modern materials.
The pyramid would cost $1.2 billion to build.
At 455 feet tall, it was the tallest building in the world from the time of its completion around 2560 BC to 1311 AD. Currently, the Burj Khalifa is the tallest structure in the world, but no building has held the title for as long.
