In building the Third Pylon, Amenhotep dismantled a number of older monuments, including a small gateway he himself built earlier in the reign. He deposited hundreds of blocks from these monuments inside the pylon towers as fill. These were recovered by Egyptologists in the early 20th century and led to the reconstruction of several lost monuments, including the White Chapel of Senusret I and the red chapel of Queen Hatshepsut, which are now in the open-air museum at Karnak.
