Where is the Westwood Wildcat Clue #4

Okay, now that we know what country the wildcat is in, lets see a bit of history on his hiding place.

He is up in the Peruvian Mountains in the ruins of an ancient city.  This city was built around 1450, but was abandoned 100 years later when Spanish explorers came in and caused their empire to collapse.  This amazing city was rediscovered in 1911 with most of its buildings still in tact.
