This first Egyptian pyramid consisted of six mastabas (of decreasing
size) built atop one another in what were clearly revisions and
developments of the original plan. The pyramid originally stood 62
metres (203 ft) tall, with a base of 109 m × 125 m (358 ft × 410 ft) and
was clad in polished white limestone. The step pyramid (or
proto-pyramid) is considered to be the earliest large-scale cut stone
construction, although the nearby enclosure known as Gisr el-mudir would
seem to predate the complex. The oldest known unworked stone pyramid
structure dates to 3000 BC in the city of Caral, Peru
