The horizontal passage leads to rooms consisting of a funeral serdab, an antechamber, and a burial chamber. All three are aligned along an east–west axis. The only peculiarity of the serdab is the size of the block ensuring its coverage, measuring 6.72 metres long with a weight of forty tons. The antechamber and burial chamber are covered with huge vaulted rafters. They are connected by a passage where access was closed by a double door. The walls of these rooms are covered with hieroglyphic inscriptions commonly called Pyramid Texts. The pyramid of Teti is the second royal monument to contain the complex theological corpus to assist and support the rebirth of the king.
