a.k.a. Khufu’s Pyramid, Tomb of Cheops, Khufu (with Khufu being a fourth dynasty Egyptian pharaoh)
The approximately seven–year construction was the world’s highest manmade structure, at 480.9 ft or 146.6 m, until 1300 CE, although height was certainly not its primary defining historical significance.
Note: The Great Pyramid was not surpassed in height until 3,652 years later, by the Lincoln Cathedral in Lincoln, England, in 1300.
