A recent study describes the examination of a set of 13,800-year-old rock carvings in Spain that are believed to be the oldest depictions of a human settlement found thus far.

Ancient cave drawings have been found before, but a set uncovered in 2013 in Spain is considered particularly unique because of its subject. 
A recent study describes what may be the oldest-known representation of a human social space, possibly in the form of a “hunter-gatherer campsite.” 
A close inspection of the stone slab shows seven separate carvings which appear to resemble huts. 
This art is thought to have been created about 13,800
