Boncuklu Tarla is an archaeological site in the Southeastern Anatolia of Turkey. It is the remains of a settlement occupied from the Late Epipalaeolithic to Pre-Pottery Neolithic B periods. It was discovered in 2008 during an archaeological survey in advance of the construction of the Ilısu Dam and has been excavated by a team from Mardin Museum since 2012. The discovery of a large communal building with stone pillars was reported at Boncuklu Tarla in 2019, prompting comparisons to Göbekli Tepe. It is an early example of rectangular plan architecture. The excavators also claimed to have found a sewer system, which if confirmed would be the oldest known in the world. From Wikipedia
