Church (building)
In the early days of Christianity people met in private buildings. Church buildings are mentioned for the first time around the year 260 A.D. when the Emperor Galienus ordered an end of a persecution and to return the places of worship. In the third century we hear of large church buildings. We do not know, how these early buildings looked. Only in Dura-Europos (Syria) a building was discovered, which had been a private house modified for Christian services.
