Just west of the viewing point, you can look down into an archaeological  trench and see the natural bedrock twenty strata below. The first city-like settlement on the natural hill dates from the Chalcolithic period. It includes a rectangular sanctuary. But the main attraction is a round altar or high place dating from about 2700 BC, the Early Bronze Age. It is surrounded by a low wall. Between the altar and the wall, the American archaeologists found a large quantity of animal bones (no human!). This altar was in use for seven centuries. Large temples were built near it, dating from about 2100 BC. The current expedition is discovering older temples beneath them.
