The stones of Stonehenge have been there for millennia, yes, but they are only in their modern configuration since the 1950s, as a best guess reconstruction of something that had been lost long ago.

The Bamyan statues were much younger, but were largely intact as they had been for 1,400 years. And, y'know, got blown up rather than doused with a bit of colour (which frankly was probably a better recreation of what happened at the real Stonehenge than the LARPing the faux druids do).
