A church is a building used for worship service or other religious activities in Christianity. In traditional Christian Church designs, the church’s plan view often forms a cross. The center aisle and seating represent the vertical beam, while the altar and bema from the horizontal beam. Modern church designs may have different layouts, and many churches have been converted from buildings designed for other purposes.

The earliest identified church is the Duras-Europas church in Syria, which was founded between 233 and 256. It is believed to be a normal domestic home converted for worship.

Churches vary greatly in types and sizes. The types of churches include basilica, cathedral, pilgrimage, conventual, and collegiate. Cathedrals are usually Catholic, Anglican, Oriental Orthodox, or Eastern Orthodox.
