Discover the Great Pyramids of Egypt

The largest pyramids are built from millions of individually cut stone blocks, an achievement that remains genuinely impressive given the tools and techniques available in the Bronze Age. Each pyramid was precisely aligned so its four sides face true north, south, east, and west -- an accuracy that reflects both careful surveying and the solar-based religious beliefs that shaped the pyramids' design.

The largest pyramids were originally faced with polished white limestone casing stones, with the capstones likely gilded -- a finish that made them sun-reflective and considerably more striking than the exposed stone visible today, since most of that outer casing was later stripped for reuse elsewhere. Most pyramids also contain intricate internal passages and burial chambers reaching deep into the structure.
