The wall that was already ancient when the pyramids were built
The oldest paintings at Bhimbetka predate the pyramids by roughly 25,000 years. The Egyptians were still millennia away when someone crouched in these Vindhya hill caves and pressed ochre into stone to record a bison mid-charge. That bison is still there. You can stand close enough to see the individual brushstrokes, and there is no rope, no glass, no tour group between you and it.
