Following excavations at the necropolis of Nuri, Reisner proposed to attribute the pyramid Nuri 20 to Atlanersa on chronological grounds.
Nuri 20 is the second-oldest pyramid of the necropolis after that of Taharqa and did not belong to Senkamanisken, whose pyramid Nuri 3 was built subsequently.
Reisner's arguments have been broadly accepted.
Atlanersa was the second king, following Taharqa, to choose Nuri for burial; this fact motivates certain specialists—including Török, Timothy Kendall and El-Hassan Ahmed Mohamed—to posit that Atlanersa was Taharqa's son, and that he chose this necropolis to be close to and honor his father.

The pyramid is made of sandstone masonry, with a steep slope at 66° and a surface area of c. 12.09 m² (130.1 sq ft).
The pyramid complex is surrounded by a sandstone enclosure and comprises a small chapel adjacent to the pyramid eastern side.
At its center, the chapel housed an offering stand on which was an offering table, both of grey granite.
The table was originally inscribed with reliefs and hieroglyphs, now illegible.

The pyramid substructures were accessed from a stair of 36 steps, starting at ground level east of the chapel.
At the end of the staircase was a wall of masonry meant to bar thieves from entering the tomb, which comprised two chambers.
The antechamber is 2.6 m × 2.5 m (8.5 ft × 8.2 ft) in size, while the burial chamber is larger at 5.65 m × 3.75 m (18.5 ft × 12.3 ft).
The latter contained a lid and several fragments of canopic jars, 11 or 12 canopic clay figures of gods and goddesses including Osiris, Imsety and Neith, a few inlay pieces of lapis lazuli, obsidian and slate (all originally from a sarcophagus), and fragmentary faience shawabtis.

Excavations of the pyramid yielded numerous objects including fragments of jars and alabaster vessels, one of which was inscribed with Tantamani's cartouches, several bowls, a beryl scarab attached to a gold wire loop, pieces of gold foil, a faience pendant with Atlanersa's cartouche, Menat amulets and beads, pieces of paste, and further fragments of shawabtis.
In total, 15 complete shawabtis were recovered of over 235 found in the pyramid, all c. 15 cm (5.9 in) in size.
Many of these objects are now on display at the Boston Museum of Fine Arts.

A nearby rectangular building of brown sandstone, now known as Nuri 500, may have been a funerary chapel.
It yielded an alabaster votive tablet bearing Atlanersa's cartouche.
