This is what you see inside the Red Pyramid in Egypt. It is said to be the world’s oldest true pyramids. This is located at Dahshur, 20 kilometres away from the famous trio of Pyramids in Giza. Don’t be fooled by its name though. The whole facade of the pyramid has nothing red on it. It derives its monicker from the red limestones that you’ll see when inside.
Be also aware that going inside the Red Pyramid is not for those with weak bones. You’ll be going down on a 63-meter tunnel with your back hunched all the time. If you’re claustrophobic, don’t even dare to try.
