The complex was first investigated and identified as a pyramid by Arthur Mace and Charles T. Currelly between 1899 and 1902 on behalf of the Egypt Exploration Fund.

Mace also dug a tunnel under the pyramid, in order to locate a hypothesised lower chamber.

[1] Since 1993, new excavations have been undertaken on the complex by Stephen P. Harvey, which have identified numerous relief fragments and made clear that the Tetisheri-chapel is a pyramid.

Various rulers of the preceding 17th Dynasty had had tombs there in the form of small pyramids, which did not measure more than 10 metres in length.

[4][5] The mummies of Ahmose and Tetisheri were found in the Royal Cache at Deir el-Bahari, where they were brought in the 22nd Dynasty to protect them from grave robbers.

[6] The cult of Ahmose in the Pyramid and its temple complex is known from a stele inscribed about three hundred years later in the reign of Ramesses II.

The inscription records that a processional boat of the cult of Ahmose was used by the locals as an oracle of the deified king.

[3] The pyramid measured 52.5 m (172 ft) on each side, which corresponds to 100 royal cubits, and consisted of a core of rubble and sand, which was hidden with a cladding of fine limestone.

[1] After the cladding was spoliated in later times, the core lost its coherence and spread out, becoming the ten-meter-high rubble mound that exists today.

The core material might have derived from excavation of the underground Grave of Osiris in the southern part of the complex.

[1] The existence of chambers within the superstructure of the pyramid can be ruled out because of the looseness of the rubble and sand core.

This structure was falsely identified by earlier scholars as a cult pyramid [de] on account of its location.

In this inscription, Ahmose tells his wife about his plans to erect a pyramid as a memorial for Tetisheri, who was buried in Thebes.

My Majesty wishes, that a pyramid and a funerary temple be erected for her near my memorial in the sublime land."

Excavations revealed fragments of the pyramidion, which indicates that the angle of inclination was similar to that of Ahmose's pyramid.

The tomb is located on the orientation line running from the pyramid to the terrace temple, like the other buildings of the complex.

Votive offerings in the form of ceramic vessels, models of boats, and stone vases were found here.

Above this, a corridor led south to a small chamber, where there was probably a statue of the ruler standing on a podium.
