The pyramid of Sahure reached 47 m (154 ft) at the time of its construction, much smaller than the pyramids of the preceding 4th Dynasty. Its inner core is made of roughly hewn stones organized in steps and held together in many sections with a thick mortar of mud. This construction technique, much cheaper and faster to execute than the stone-based techniques of the 4th Dynasty, fared much worse over time. Owing to this, Sahure's pyramid is now largely ruined and amounts to little more than a pile of rubble showing the crude filling of debris and mortar constituting the core, which became exposed after the casing stones were stolen in antiquity.
While the core was under construction, a corridor was left open leading into the shaft where the grave chamber was built separately and later covered by leftover stone blocks and debris. This construction strategy is clearly visible in later unfinished pyramids, in particular the Pyramid of Neferefre. This technique also reflects the older style from the 3rd Dynasty seemingly coming back into fashion after being temporarily abandoned by the builders of the five great pyramids at Dahshur and Giza during the 4th Dynasty.
The entrance at the north side is a short descending corridor lined with red granite followed by a passageway ending at the burial chamber with its gabled roof comprising large limestone beams. Today these beams are damaged, which weakens the pyramid structure. Fragments of the sarcophagus were found here in the burial chamber, when it was first entered by John Shae Perring in the mid 19th century. The colossal roof blocks of Sahure's temple weighed up to about 220 tons based on estimates by Perring. He estimated the size of the largest blocks at 35 feet by 9 feet by 12 feet. One end of these blocks was tapered so the estimated volume is 95 cubic meters or 2.4 tons. The mortuary complex immediately around the pyramid also comprises a second pyramid built for the Ka of the king.
