The pyramid of Pharaoh Merenre was constructed for Merenre Nemtyemsaf I during the Sixth Dynasty of Egypt at Saqqara 450 metres to the south-west of the pyramid of Pepi I and a similar distance to the pyramid of Djedkare. Its ancient name was "Merenre's beauty shines" or perhaps "The Perfection of Merenre Appears". Today it consists mostly of ruins; it is hard to get to and is not open to the public.
The pyramid was built 52.5 metres in height, 78.75 metres in base length with an inclination of 53°07'48". The causeway is 250 metres long and the complex was surrounded by a wall of mud brick.
