Tell er-Retaba (Arabic تل الرطابة Tall ar-Raṭāba; also spelled Tell el-Retaba, Tell er-Retabeh) is an archaeological site in Egypt. It is located in the eastern Nile Delta region of the semi-arid Wadi Tumilat. The oldest artifacts date from the 9th and 12th Dynasties of ancient Egypt. Major construction activity took place during the New Kingdom. The temple complex of "Atum, Lord of Tjeku" dates from the time of Ramses II. Since no further traces of settlement have been found for the period after 600 BC, it is assumed that the site was abandoned in favor of Tell el-Maschuta.
Some researchers, such as Manfred Bietak and Kenneth Kitchen, have identified Tell er-Retaba with the biblical Pithom, which is mentioned in the Book of Exodus (Exodus 1:11) alongside Pi-Ramesse as a settlement of the Israelites from which they departed from Egypt.
This opinion goes back to the 19th century, when Alan Gardiner first identified Pithom with the site of Tell El Retaba, and this was later accepted by William F. Albright, and Kenneth Kitchen. Although John van Seters and Neil Asher Silberman argue that Tell El Retaba was unoccupied during the period when we find monuments relating to a town called Pithom, this claim has been disputed by James K. Hoffmeier and Gary Rendsburg based on recent findings at the site.
The identification with Pithom is not definitive, as the successor settlement of Tell el-Mashuta is also a possibility.
The fortified city of Tell er-Retaba was the only major settlement in Wadi Tumilat during the New Kingdom and was uninhabited only from 600 to 400 BC. These findings suggest that it is highly likely Tell el-Maschuta was founded a short distance further east after Tell er-Retaba. During this period, Necho II (610–595 BC) commissioned the construction of a canal to the Red Sea, which ran through Wadi Tumilat.
The older Ramesside and Third Intermediate Period monuments originating from Tell el-Maschuta must therefore have been transported there at a later date. Kenneth Kitchen disagreed with this reconstruction. In his opinion, Tell er-Retaba (Pithom) and Tell el-Maschuta (Tjeku) existed simultaneously as significant settlements during the New Kingdom. However, Kitchen disregarded the ceramic evidence in his hypothesis.
Ramses III also erected monuments at this site and reinforced the fortress.
Since 2007, the site was investigated by a joint Polish-Slovak Archaeological Mission.
