Göbekli Tepe was declared as a World Heritage by UNESCO in 2018. The site is from 11000 to 12000 BC, Neo-Lethic pre-pottery periods. This area is part of Upper Mesopotamia, a region known for introducing ancient farming. It is also known for its T-shaped large lime stone structures having animal shape carvings. The site provides an intuition into earliest proofs of a community employing engineering technology by skilled craftsmen. This site has all the indications of initial existance of a hierarchical structure in a society.
