The ancient Egyptians had an advanced understanding of planning and engineering, as proven by the sturdy pyramids built between 2589 and 504 BC. These royal tombs were constructed to hold the remains of pharaohs, and often consisted of multiple rooms and indoor courtyards. The pyramids were beautifully decorated with hieroglyphics and included false doors, representing the connection between the living and the dead. The Great Sphinx, one of the oldest and largest statues in the world, was built to stand guard over the Pyramids of Giza. While efforts are being made to preserve the Great Sphinx, it continues to erode. It might be now or never to cross the Egyptian pyramids and Great Sphinx off your bucket list.
