Built more than 4,000 years ago, the Great Pyramid of Giza in Egypt was 481 feet tall – close to the height of a 50-story skyscraper! Constructed of more than 2.3 million stone blocks, the Great Pyramid was a colossus. After learning about different types of pyramids and ziggurats, kids will collaborate to build their own. This is an in-person program that meets at the Skyscraper Museum, 39 Battery Pl. Masks are required for indoor programs.
