A church building, often simply called a church, is a building used for religious activities, particularly worship services. The term in its architectural sense is most often used by Christians to refer to their religious buildings; they can be used by other religions.[1] In traditional Christian architecture, the church is often arranged in the shape of a Christian cross. When viewed from plan view the longest part of a cross is represented by the aisle and the junction of the cross is located at the altar area.
