During excavations at the pyramid complex of Netjerkhet at Saqqara in the 1920s, Firth and Quibell discovered a purpose-built archive with fragments of papyri still in situ. Although this important discovery received scant notice in the published reports, it can be determined that the archive was constructed when ”Temple T” or the ”Building with three fluted columns” was converted into an administrative centre around 2400 BC. The archive consists of a long corridor flanked by 26 mud-brick niches and it had the estimated capacity to store several thousand papyri. The contents of the papyri found in the niches suggests that the administrative centre was used by the vizier and that it was involved in the construction of the royal pyramids during the late Old Kingdom.
