The precinct is by far the largest of these and the only one that is open to the general public. The temple complex is dedicated to the principal god of the Theban Triad, Amun, in the form of Amun-Re.
The site occupies roughly 250 000 m², containing many structures and monuments.
Most of the southwest is an open-air-assembling area with millions of stone fragments, from small to huge, laid out in long rows, awaiting reassembly into their respective monuments.
The area is not closed, as the temples of Khons and Opet both lie in this corner and are open to the public, though both are rarely visited considering the immense number of tourists coming to Karnak.
