In 1927, the dismantled pieces were found inside the Third Pylon of the main temple, constructed in the time of Amenhotep III, at Karnak, and between 1927 and 1930 all of the pieces were carefully removed. These pieces were then assembled into the building that is seen today in the Karnak Open Air Museum.
The White Chapel is made of limestone. Its columns hold reliefs of a very high quality, which are hardly seen elsewhere at Karnak, and depicts Pharaoh Senusret being crowned and embraced by Amun, Horus, Min and Ptah.
All along the base of the outer walls runs a series of reliefs depicting the emblems and deities of the nomes, or provinces, of Egypt. On the western side are the nomes of Upper Egypt, and on the eastern side are the nomes of Lower Egypt.
