The Open Air Museum is located across from the Great Court, opposite to the entrance of Ramesses III Temple. It has a collection of monuments that was discovered during an excavation inside the third pylon. We can find blocks from the beautiful Red Chapel of Hatshepsut . That Chapel served as a shrine for the baroque of Amun and whose site is today occupied by the chapel of Philip Arhidaeus.

We can see the remains of the splendid White Chapel of Senwosret I. The scenes carved on the stones show the kings' offering to his mighty god Amun- Re and Amun in his ithyphallic form. The ancient administrative areas of Egypt are listed in the form of columns on the parapet. The entire region of Egypt is represented on the chapel of the Pharaoh who is the guarantor of the order established by Amun.

The Alabaster Chapel of Amenhotep I is located north of the museum. It is considered the oldest shrine for Barque. Inside, the king is shown presenting offerings to the sacred barque.

At the end of the museum, is a reconstructed summit of a small pylon constructed by Thutmose II. It was rebuilt by Thutmose IV and called the Festival Court. It was supposed to be situated in front of the fourth pylon on the site of the eastern side of the Hypostyle Hall.
