Okay, so we're going for a ride around the pyramids.
The Great Pyramid was the tallest man-made structure for nearly 4,000 years, only surpassed by a large margin by the Eiffel Tower in 1889.
147 meters high.
You are interested by climbing?
Yeah, let's climb it.
But it's not free.
How much?
What makes the pyramids even more impressive is that these structures were built over 4,500 years ago.
When Egyptians didn't have wheels or steel, the only metal available was copper and copper alloys.
It took about 2 million stones to build that pyramid.
