Yumuktepe (or Yümüktepe) is a tell (ruin mound) at within the city borders of Mersin, Turkey. In 1936, the mound was at the outskirts of Mersin. But after the rapid increase of population, now the mound is in the Toroslar municipality of Mersin.
Discovery and excavations
Excavations during 1936-1938 period by British archaeologist John Garstang (1876–1956) who is the founder of British Institute at Ankara, have revealed a neolithic settlement which continued up to medieval ages. However, the excavations halted during World War II and some documents in the Liverpool University have been lost after an air raid. After the war, John Garstang as well as Veli Sevin of İstanbul University and Isabella Caneva  of Sapienza University of Rome continued the excavations.
There are 23 levels of occupation dating from ca 6300 BC. In his book named Prehistoric Mersin Garstang lists the tools unearthed in the excavations . The earliest tools are made of either stone or ceramic. Both agriculture and animal husbandry (sheep, cattle goats and porke) were among the economic activities in Yumuktepe. In the layer which corresponds to roughly 4500 BC, one of the earliest fortifications in human history exists. According to Isabella Caneva, during chalcolithic age an early copper blast furnace was in use in Yumuktepe. Probably Yumuktepe was a coastal settlement. But because of the alluvion carried by the nearby river Müftü, now the mound is 2.5 kilometres (1.6 mi) north of the Mediterranean shore.
During historical era, Yumuktepe was a part of Kizuwatna a vassal kingdom of Hittite Empire. In a document of 1440 BC, the city of Pitura had been mentioned. Pitura might be the ancient name of the settlement. It seems, like most Hittite lands, sea people from Europe plundered Yumuktepe in 13th century BC. A second blow was from Assyrian Empire from Upper Mesopotamia. During Roman Empire, Yumuk was a relatively unimportant city named Zephyrium . But Emperor Hadrian (reigned 117-138) renamed the city as Hadrianapolis. During early Byzantine Empire, the nearby settlement of Soli (10 kilometres (6.2 mi) at the west) flourished and Yumuk was abandoned.
