Giza: Great Pyramid of Khufu

It's so big that looking from the base to the sky, it's hard to see the top.

When built, the pyramid would have stood 147m tall, but it's now missing some of its pyramidion (apex capstone) and currently stands at approximately 139m. It was the tallest building in the world for 3800 years.
