I've been to Gobeklitepe. Amazing place. What has been dug so far is a small fraction of what's under the surface yet.
These round structures are intriguing. It's thought to be temporary. People came from all directions, built these, stayed for a while, ate a lot of hunted animals, and they buried these structures to never use again. Why? We don't know.
I should visit Karahantepe too. Looks as interesting.
