<em>Dura-Europos</em> was an ancient city located in the vicinity of village of <em>Salhiyé</em>, Syria, along the Euphrates river, close to the Iraq border.
Christian places needed to be discreet or secret around 240 A.D.; thus earlier congregations worshiped in private houses of wealthy members; some of those houses were converted into churches, and the house in <em>Dura-Europos</em> was one of those conversions.
