Nowhere else is the singular lintel structure of Stonehenge to be found. Nor is there any other example of the tongue and groove interlocking construction which has enable this drystone building to stand against the passage of Time for almost four thousand years.

Saqqara, Egypt, ca. 2630-2611 BC

There are two Step Pyramid Complexes on the Saqqara plateau. One belongs to Phaoroh Zoser and the other to his successor, Sekhemkhet, the ruins of which were discovered in 1951. In both these complexes the step pyramid is built at the centre of a rectangular Open Court. There is, however, archaeological evidence of two huge Open Courts without pyramids or tombs, lying to the west of these structures.  Sakkhara  is derived from Sokar, and agricultural god believed to dwell in the earth.
Dominating the horizon at Saqqara is the Step Pyramid, the central feature of a funerary complex built by Imhotep for his Pharaoh Zoser, the first king of the 3rd Dynasty. Zoser exercised complete political and religious control over the Two Lands of Upper and Lower Egypt. His reign marks the beginning of the Old Kingdom, an era of great vision and invention.
The Funerary Complex is symbolic. It was fashioned after the existing structures of the state capital, in order for the pharaoh to repeat in the afterlife his earthly experience. All the principal elements are presented in pairs, indicating that all rituals and activities were carried out twice: in the pharaoh's capacity first as King of Upper Egypt, and then as King of Lower Egypt. Naturally the monuments shed much light on the functions of the pharaoh, and the manner in which the distant provinces of Egypt were brought into relationship with the central power.
Zoser's vizier architect, Imhotep, the first architect whose name has been recorded in history, chose to build his pharaoh's funerary complex in stone. Until this time royal tombs had been built of sun-dried brick. Stone had been used for doorways or for the flagstones of a tomb chamber only. Imhotep therefore had no architectural tradition from which to draw, and was obliged to turn to existing forms. He observed the bundles of reeds tied together at the corners of brick structures with heads fanning out, and, transcribed into stone, these became the fasciculated column with capital seen in the entrance colonade; he simulated in stone the logs placed edgewise to form a roof; palm stalks, reed fences, matting, papyrus and other soft materials of which the contemporary houses were constructed, and which have all perished, thus became petrified in a medium that lent itself to stateliness and austerity.
The importance of this funerary complex is therefore twofold. It mirrors the structures of the state capital, from which we can glean the administrative and religious activities at the time; and, faultlessly copyies nature's themes. Imhotep created a diversity and originality of architectural style that has never been surpassed. He bequeathed a legacy to which architecture, through the Greeks and Romans, was to return time and again.

Three architectural inventions appear for the first time in world history at Saqqara
  • Ashlar masonry. The Third Dynasty funerary precinct of Zoser at Saqqara is the first major architectural enterprise to be executed in stone throughout. Moreover, the fine limestone blocks are in ashlar masonry. That is, they are parallelepipeds, six-faced regular solids of standard sizes, laid in regular horizontal courses. Before this, such monuments were of mud brick. Imitating the regularity of the six-  faced bricks (top, bottom and four sides), the Saqqara limestone blocks are examples of skeuomorphism, a learned term for the migration of a form native to one medium into another. Once invented, ashlar masonry had a great future. One thinks of the walls of Greek monumental buildings, not to mention countless stately banks, libraries, and governmental buildings of our own time—all executed in ashlar masonry. It is sometimes assumed, by the way that standardization is a product of our own industrial age. However, standarized bricks and limestone blocks long preceded it.
  • Modularity. The invention of ashlar is probably the first instance of the principle of modularity—the regular "scansion" of space using architectural means. A kind of negative version appears in the regular bays of Egyptian temples and hypostyle halls.
  • Columnar architecture. The Saqqara complex shows several types of engaged (attached) columns. Later, the columns are freestanding, surmounted by capitals, and marshaled into rows (colonnades). Indebted to Egypt, columnar architecture was fundamental in ancient Greece, Rome, and the Renaissance.
