The Dura-Europos synagogue was an ancient synagogue uncovered at Dura-Europos, Syria, in 1932. The synagogue contains a forecourt and house of assembly with painted walls depicting people and animals, and a Torah shrine in the western wall facing Jerusalem. It was built backing on to the city wall, which was important in its survival. The last phase of construction was dated by an Aramaic inscription to 244 AD, making it one of the oldest synagogues in the world. It was unique among the many ancient synagogues that have emerged from archaeological digs as the structure was preserved virtually intact, and it had extensive figurative wall-paintings, which came as a considerable surprise to scholars. These paintings are now displayed in the National Museum of Damascus.
Dura-Europos was a small garrison and trading city on the river Euphrates, and usually on the frontier between the Eastern Roman Empire and the Parthian and finally the Sassanid Empires of Persia.
