IAA describes Tel Nissa as a large tall mound about 75 x 100 meters in area and at least 15 m high. Springs which form the perennial stream Wadi el-Manshiya, which flows toward the Jordan River issue forth at the southwestern foot of the tell. The site is further described as follows:

Stone and mud brick walls are exposed on the tell’s eastern and southern slopes, while a brick building that is a kind of tower is exposed in the extreme southern corner. Numerous pottery sherds and other artifacts were gathered on these slopes, including some dating to

• Early Bronze Age I – holemouth rims and other pottery sherds
• Late Bronze Age – most of the sherds are from this period and include fragments of vessels with painted parallel stripes that form a reticulated or crisscross pattern and a design of a winged-animals
• Iron Age I – small bowls that have a pointed rim decorated with a red stripe, lamps, a zoomorphic handle (Fig. 1) and a jug that has a filter and a spouts
• Iron Age II – small bowls burnished on the inside, carinated rims, cooking pot handles, wo alabaster vessels, two small bowls of the type that were found at Bet Shemesh and at Tell Abu Hawam, a zoomorphic vessel, ovoid loom weights made of limestone and indigenous alabaster and a bronze arrow.

Numerous flint tools were gathered in the channel of the stream and next to the springs at the foot of the site:

• Paleolithic period – a Levallois-Mousterian blade
• Neolithic-Chalcolithic period – flakes, blades and axes
• Early Bronze Age – blades and sickle blades that have straight sides; as well as coarse flakes with polished cutting edges, probably dating to the Iron Age.

Roman and Byzantine coins were gathered in the fields of Kibbutz Neve Eitan, between the last two sites.

There was a flat knoll with remains of a basalt building on it in what is now an enclave in a planted area and the fishponds located c 100 meters south of Neve Eitan. Ribbed sherds from the Late Byzantine period were collected there.
