The Karnak Open Air Museum occupies a courtyard in the northeast corner of the main Karnak enclosure, displaying monuments that have been reassembled from blocks found scattered across the site. It is a quieter corner of Karnak, typically bypassed by tour groups, but it contains some of the finest individual pieces in the complex.
The star exhibit is the White Chapel of Senusret I, a Middle Kingdom limestone kiosk with superbly preserved reliefs. There is also the Red Chapel of Hatshepsut (Chapelle Rouge), a pink granite sanctuary that was dismantled by later pharaohs and reassembled by archaeologists. The contrast between these two structures — one from the 12th dynasty, one from the 18th, separated by 500 years — shows the continuity and variation in Egyptian temple building. Entry is usually included with the main Karnak ticket; ask at the entrance.
