The site of En Esur consists of three elements: Tel Esur, which is the main tell (a mound of accumulated human settlement layers) covering c. 28
dunams, a smaller mound southeast of it, and an open field that surrounds the mounds, which was occupied by a massive, densely built city during the Early Bronze Age. Little is known about this phase; no traces of structures were found, and only a few artefacts.
Chalcolithic Early Chalcolithic . In addition to the road, the site has been disturbed by modern developments including several buildings and a reservoir. The site was occupied throughout the Early
Chalcolithic period, founded around 5000 BC. There were only scattered finds from Early Chalcolithic I and a small occupation in Early Chalcolithic III. It was during the Early Chalcolithic II (EC II) period that the site became a significant place, reaching a size of 50 hectares. The archaeologists uncovered a c. 60 m2 large area, free of dwellings, used for cultic activities. This would have made the settlement much larger than
Tel Megiddo in Israel and
Jericho in the
West Bank, and therefore the largest settlement in the
Southern Levant during this period, but smaller than more distant cities in Egypt and Mesopotamia. Archaeologist Itai Elad stated that En Esur is double the size of other large settlements known in the area. Archaeologists excavating the site believe that the city was planned, and included not only streets, alleys and squares, but also facilities for storage and drainage, and a cemetery. En Esur was surrounded by fortified walls that were high. The inhabitants of En Esur are thought to have been an agricultural people. They would have traded with other regions and kingdoms. which was located in a public area and includes a courtyard with a huge stone basin for rituals. The Tell el-Asawir
necropolis, located near a stone quarry, underwent a salvage excavation in 2003, resulting in a find presented to the press as "the largest Bronze Age necropolis in the world". The
Ministry of Religious Affairs intervened and the thousands of human skeletons excavated from burial chambers measuring up to 100 m2 had to be reburied before they could be scientifically studied, although their age excluded the possibility of them being the remains of Jews, which are not to be disturbed under
Jewish religious laws. In Egypt, the rise of the 1st Dynasty with Narmer and Aha occurred in the final EB IB, with Djer marking the transitional EB IB/EB IIA. Trade centers in Lower Egypt, such as
Tell el-Farkha declined with trade routes changing. Climate conditions during the EB II (c. 3050/3000-2750/2720 BCE) were generally drier before they improved in EB IIIA (c. 2720-2500 BCE), but 'En Esur did not revive as an urban center for the rest of EBA.
Middle Bronze Age Unlike Tel Bet She'an, Tel Megiddo and other sites in the Levant, there is no evidence of a return to urbanization in the following
Middle Bronze Age.
Iron Age Administrative center In excavations led by S. Bar in 2010–2014 on the western slopes of the small mound (Area D), a large public structure from the early 8th century BCE (Iron Age IIB) came to light. The fortified tower abutted by a storehouse was interpreted as being part of a regional administrative centre, due to similarities with other contemporary public complexes. ==Preservation==
