Why the Secret Door of the Great Sphinx is Never Opened

here are many stores around the world that have been closed for decades or even centuries. The question is why. Nowadays, it seems like any door can be opened. However, some doors were sealed for a grave reason, and their treasures and mysteries remain undiscovered. Here are four doors that keep their secrets well. First, there's the Taj Mahal in India, commissioned by Shah Jahan in 1631 as a tomb for his beloved third wife. The construction took 20 years, and the building has an unusual layout with four tall minarets. There are sealed rooms all over the place that nobody is allowed to enter, and two basements that are also sealed up. Some researchers think that these rooms were built using marble that turns into a different substance when exposed to carbon dioxide. There's no air flowing into these rooms, which could cause the minarets to collapse. Some people even believe that Shah Jahan's wife's body is in one of these sealed rooms. The Great Sphinx of Giza is also shrouded in mystery. It's the largest monolith statue in the world and has a woman's head and a lion's body.
