The cult pyramid had a core ascending in two or three steps, composed primarily of limestone block debris framed by yellow limestone blocks, and then encased with white limestone blocks – the same method of construction as used in the main pyramid. It had a base length of converging at 56° towards the apex high. From the north face, a bent corridor – initially descending, then switching to an ascent – leads into the miniature pyramid's sole chamber: an east–west oriented burial room slightly below ground level. The chamber was found void of any content, and its walls had been severely damaged by stone thieves.
