and the storerooms surrounding this courtyard to the east, north and south. No Middle Kingdom remains are visible, and it would have been better to name it the "New Kingdom" courtyard. Since, however, this space has long been known as the "Middle Kingdom," it will be designated here as the so-called "Middle Kingdom" courtyard. Limestone radier: A stone foundation platform covering the entire surface to be built upon.The limestone radier refers to the thick foundation (height: 3 cubits) made of thin courses of small limestone blocks, which is buried under the surface of the so-called "Middle Kingdom" courtyard. The blocks are all reused and were produced by cutting off the faces of larger blocks. Platform: A foundation made of flat blocks of sandstone, limestone and granite, which occupies a small surface of less than 100 m 2 , and built at the west side of the limestone radier. The blocks are all reused and at least two limestone blocks are decorated. Storerooms surrounding the radier: A group of 10 storerooms was built around the east, north and south sides of the limestone radier from which they are separated by a Ushaped corridor. Set on a thick layer of sand, their foundations are made of two green sandstone courses surrounding the limestone radier. Enclosure tied to the 5 th Pylon: This enclosure is made up of four perpendicular walls delimiting a wide rectangular space, the west one being divided by the Pylon. Each half of this west wall is bonded to the Pylon and to the north or south enclosure walls, while the east wall is perpendicular to both the north and south ones. The Akh-menu abutts the east face of this east enclosure wall. Service corridor: The north side of this corridor borders the outer wall of the storerooms 1 G.
