Older Than Djoser?

Have Researchers Found the Oldest Stone Structure in Egypt — Possibly in the World — at the Step Pyramid?

Colin Reader and Robert Partridge, Egypt Revealed magazine

An enigmatic cut-stone structure with massive walls seems to be older even than the Step Pyramid complex of King Djoser (2668-2649 B.C.) — and that would mean rewriting the history books of ancient Egypt, for the Djoser pyramid has long been cited as the oldest stone building in the world.

The vast and ancient necropolis at Saqqara was a burial ground throughout all periods of Egyptian history, from the Early Dynastic to Greco-Roman periods. Both the Step Pyramid and the new stone structure, called the Gisr el-Mudir ("Enclosure of the Boss"), are at Saqqara.

Little of this large, rectangular structure remains on the surface, although it was first identified in aerial photographs in the 1920s. Ian Mathieson, director of the National Museums of Scotland's Saqqara Survey Project, and his team used modern geophysical surveying techniques to explore beneath the surface of the desert without expensive and speculative excavations. 

Mathieson established that Gisr el-Mudir is more than 600 meters (1,975 feet) long and 400 meters (1,300 feet) wide. No major structure, such as an unfinished pyramid, has been found within the enclosure, leading to considerable speculation over its purpose.

After electronically mapping the area, the project excavated test trenches to determine exactly what the underground anomalies found by the geophysics represented. The team almost immediately encountered stone blocks of the base of the huge wall surrounding the site.

The wall, about 15 meters (50 feet) wide at the base, was built with an inner and outer skin of local limestone and a central core filled with sand and rubble. Artifacts recovered from this fill date the enclosure to the Second Dynasty (around 2900 B.C.). Thus the Enclosure of the Boss becomes the world's oldest-known stone-built structure. 

Many of the stones used in the structure have been looted over the millennia — in fact, the builders of Djoser's pyramid may well have used the site as a rather convenient quarry.
