Part of the church, vestibule located in front of the main entrance, sometimes also in front of the side entrance, into the aisles or sacristy. In Great Britain the projecting porch had come into common use in churches by early medieval times. They were usually built of stone but occasionally were of timber. Normally they were placed on the south side of the church, but also on the west and north sides, sometimes in multiple. The porches served to give cover to worshipers, but they also had a liturgical use. At a baptism, the priest would receive the sponsors, with the infant, in the porch and the service began there. In later medieval times, the porch sometimes had two storeys, with a room above the entrance which was used as a local school, meeting room, storeroom, or even armoury. If the village or town possessed a collection of books, it would be housed there.
