Cordoned off structure inside the Karnak temple in Luxor

The Karnak temple was built in many sections by a number of pharaohs, and is one of the largest temple complexes inside Egypt. When inside the temple, I felt the need for a guide the maximum, since there were many structures inside that did not make sense to me, and a guide could have explained some of these.
One of these is this cordoned off structure inside the Karnak temple. It could well be the base of something much larger, such as a huge statue, but I did not anything similar to this inside the temple.
