"Standing over 3,000 years old, the Pyramids at Giza are a marvel of engineering—precise, aligned with stars and solstices, and still mystery-laden because we lack a full explanation of how they were built or how so many chambers remain inaccessible; the Great Pyramid (built by Khufu) has limited access, and I recommend visiting via a guided tour from Cairo for context and convenience." - Matthew Kepnes
