The Pyramids of Egypt, among the largest constructions ever built, constitute one of the most potent and enduring symbols of Ancient Egyptian civilization. It is generally accepted by most archaeologists that they were constructed as burial monuments associated with royal solar and stellar cults, and most were built during the Old and Middle Kingdom periods.
The number of pyramid structures in Egypt today is reported by most sources as being between 80 and 111, with a majority favouring the higher number. In 1842 Karl Richard Lepsius made a list of pyramids, in which he counted 67, but more have been identified and discovered since his time. The imprecise nature of the count is related to the fact that as many smaller pyramids are in a poor state of preservation and appear as little more than mounds of rubble, they are only now being properly identified and studied by archaeologists. Most are grouped in a number of pyramid fields, the most important of which are listed geographically, from north to south, below.
