Church of St Cosmos & St Damianus

When Christianity became the state religion under Emperor Constantine in 324, all Roman monuments that were tainted by so-called pagan practices were abandoned. These structures were subsequently pilfered for building materials as Roman cities competed with one another to build glorious churches and cathedrals. A total of 15 churches lie among Jerash's ruins, with the Church of St Cosmos & St Damianus (look for a complex with four bulbous columns and a thick outer wall) one of the best preserved.
