Largest building ever built *discovered* in Egypt

If ancient descriptions are correct, and if the recent discovery is what some think it to be, the lost Labyrinth of Egypt may be at Hawara. This was a massive temple that was described by many ancient authors, such as Herodotus, to house 3000 rooms. The walls of each room were filled will paintings and hieroglyphs. Some have presumed this labyrinth housed the lost Hall of Records, dispite other theories that place it under the Great Sphinx of Giza. I'm not going to go on about this. Just check the links.
