Abu Simbel is one of Egypt's most famous monuments, as it should be! This is an amazing work of engineering that is still well-preserved. It's amazing not only because of its amazing sculptures, but also because of the monumental entryways that were built to allow sunlight to illuminate specific parts of the chamber on certain days of the year (while still leaving the god of the underworld in darkness). It was built by Ramsses II and has another historical peculiarity: with the construction of the Aswan Dam, the temple would be submerged in water. So it had to be transported, stone by stone, in its entirety.
