Of all of Egypt's major tourist attractions, only one is at the top of any list - the Pyramids of Giza. They're Egypt's three main pyramids, built in the 4th Dynasty (circa 2550 B.C). The pyramids of Ancient Egypt were built as tombs for kings (and queens), and it was an exclusive honor to have such a tomb. However, this tradition only applied in the Old and Middle Kingdoms. Today there are more than 93 pyramids in Egypt; the most famous ones are those at Giza.
