Anatolia, also known as Asia Minor, is a large peninsula located in West Asia and a region of Turkey, constituting most of its contemporary territory. Geographically, the Anatolian region is bounded by the Mediterranean Sea to the south, the Aegean Sea to the west, the Turkish Straits to the north-west, and the Black Sea to the north. The eastern and southeastern boundary is either the southeastern and eastern borders of Turkey, or an imprecise line from the Gulf of Iskenderun to the Black Sea. Topographically, the Sea of Marmara connects the Black Sea with the Aegean Sea through the Bosporus strait and the Dardanelles strait, and separates Anatolia from Thrace in the Balkan peninsula of Southeastern Europe.
The henges in Göbekli Tepe were erected as far back as 9600 BC.

The Bosporus or Bosphorus Strait is a natural strait and an internationally significant waterway located in Istanbul, Turkey. The Bosporus connects the Black Sea to the Sea of Marmara and forms one of the continental boundaries between Asia and Europe. It also divides Turkey by separating Anatolia from Thrace. It is the world's narrowest strait used for international navigation.
