There is a massive structure hiding under a pyramid in Egypt that is like a labyrinth comprising 3,000 rooms and several passageways. This claim was made in a 2023 paper titled "The Labyrinth, The Colossi, And The Lake". Authors say they have found proof that vast underground chambers lie under Hawara in Egypt, a pyramid that doesn't look like the Giza pyramids, but it is equally massive and mysterious.
