Today, I visited (virtually) two: the tombs of Meresankh III and elite Egyptian official Menna. It was a fantastic experience. The drawings and the carvings, which are over 4000 years old are still bright and colourful, are simply breathtaking.
It takes a few minutes to understand how to navigate them the virtual space with the mouse, but you get the hang of it. There are bright white circles that show up in many places, they are virtual signboard explaining what we see and with digital reconstructions and videos.
