White Chapel of Senusret I

also referred to as the Jubilee Chapel of Senusret I. During the New Kingdom it was demolished and used as filler for the Third Pylon of the temple of Karnak, Precinct of Amun-Re. 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 King Senusret being crowned and embraced by Amun, Horus, Min and Ptah.
