Two Girls In A Church

The Syrian city of Dura-Europos on the West bank of the Euphrates was an outpost town between the Roman and Parthian empires. During a siege by Parthian troops in A.D. 257, the buildings in the outermost blocks of the city grid were partially destroyed and filled with rubble to reinforce the city wall. Thus were preserved and securely dated an early decorated church and a synagogue decorated with extensive wall paintings. Both had been converted from earlier private buildings.
The Dura-Europos church from 235 AD has a special room dedicated for baptisms with a large baptismal font.
• Medieval Europe
During the 11th through 14th centuries, a wave of building of cathedrals and smaller parish churches occurred across Western Europe. In addition to being a place of worship, the cathedral or parish church was used by the community in other ways. It could serve as a meeting place for guilds or a hall for banquets. Mystery plays were sometimes performed in cathedrals, and cathedrals might also be used for fairs. The church could be used as a place to thresh and store grain.
