The first two Queen's Pyramids, G 1a and G 1b, were likely started in year 15-17 of King Khufu. Usually Queen's pyramids were constructed to the south of the king's pyramid, but in this instance a quarry was located to the south and the construction of the smaller pyramids was relocated to the east of the main pyramid complex. The earliest part of the cemetery consisted of 12 mastabas which were built as double mastabas.
