The Great Temple of Aten it was called. All greatness is since long gone, and the 1,5 pillars standing near the most sacred of the temple should not be knocked on if you want to keep any of your illusions. They are made of fibre glass and while they look real, even close up, the sound is a different matter. While the cult of Aten was an original one in Egyptian religious history, the floor layout of the temple was based entirely on old, traditional plans. But there was no roof at any part! As Aten was the sun god, his temple could of course not keep the sun out. It was probably Horemheb who had the temple destroyed, and Ramses 2 carried much of the foundations away to build his temples ant Hermopolis.
