Of course! Because otherwise it would mean all the mystique is gone! And if the mistique is gone, people can't imagine they're supposed to be starship landing pads!

Or lay-line powered aura cleansing structures.

Or part of an ancient technology global warning system.

Or a physical star chart pointing to the origins of the Egyptians.

Or hydrogen fusion power generators.

Or piezoelectric resonance generators.

Or... Some... Other things I probably forgot about. But it's certainly, beyond a shadow of a doubt, NOT a tomb of some egotistical man that believed himself a god on the Earth!
