The satellite view shows this off much better than Wikipedia's ground-level picture. It Really is just a long band of holes dug into the side of a mountain.
At 1m diameter and 75cm deep, so ~0.59m^3, I calculate that to fill the Albert Hall, which a search suggests "has been estimated at" ~100,000m^3 (feels low to me, but it's quoted in many places), it takes around 170,000 of these Peruvian holes.

There's also some better pictures in one of the article's sources: https://web.archive.org/web/20160205050218/http://strzyzewsk...
That’s a lot of holes.
It seems obvious to me they were made by the landing pylons of heavy-lift alien spacecraft.
Even more holes than Blackburn, Lancashire.

There’s an Albert Hall where I live, it’s probably much smaller than its name sake.
I think we can fill it.
