This whole Earth is sacred in a sense. Then there are specific places where certain energies are profoundly present. Like around ley lines. You could say those are sacred areas.
The entire planet belongs to the Gods and examples of sacred places on Earth are: Giza pyramid complex, Athens in Greece or Mexican Pyramids, etc.
Besides the other answers, I would consider "adam's peek" as a sacred place as this wasn't adam's peek, but Satan's. Some mithology says that the Gods arrived to this place, I don't remember what it was called before the new name.
If this is incorrect, and we will know where the Gods landed exactly, We would probably consider that a sacred place, if it's not under water as of now.
But yes, there are some geometrically or some scientifically sacred places, areas, that would be considered sacred, just as the place where the pyramids are.
