[2][3] Senusret II had, however, taken a complete departure from the usual practice of having a corridor on the north side – typical of Old Kingdom and early Middle Kingdom pyramids[2] – and had instead built a narrow, vertical entrance shaft under a princess' tomb located about a dozen yards off to east of the southern pyramid face.

[3][12] The Czech Egyptologist Miroslav Verner explains that the decision had been made for a combination of religious reasons, and to thwart grave robbers.

The completed pyramid was originally encased in white limestone, though an inscription found by Petrie indicates that the casing was removed in the Nineteenth Dynasty for reuse in a different structure built by Ramesses II.

[16] Although Senusret II's pyramid was built with a north chapel included,[b] its real entry was hidden-away under the floor of a princess' tomb to the south-east.

[3] Instead, a larger 16 m (52 ft) deep construction shaft found further south was used for transporting the sarcophagus and building material into the substructure.

[21] An alabaster offering table inscribed with Senusret II's name, a gold uraeus, and leg bones, believed to belong to the king, are all that remained of the burial.
