The central part of a church is called an altar. This is a sacred part of the church and the place from which the sermons are preached.
Perhaps an isle; or maybe a tunnel (depending where the corridor is, upstairs or downstairs.)
A pointy part of a church roof is called a steeple. Steeples are tall structures that rise above the roofline and often serve as a focal point for the building. They are commonly found on churches and other religious buildings.
The central area of a church is typically the nave, which is the main space where the congregation gathers for worship. It is usually located between the aisles and is often lined with pews for seating. The nave is where many of the key rituals and ceremonies of the church take place.
A church is thought to be the temple of the devil. Of course it depends on your religion.
The room is called a sanctuary, the seats are called pews
The Nave is the middle part of the Church. This is where the congregation sits during the service, and is flanked by aisles on each side.
This has been a misconception for many years. The central passageway is not called an aisle, it is called the central passageway. The aisles of a church are those pathways nearest the walls.
Perhaps an isle; or maybe a tunnel (depending where the corridor is, upstairs or downstairs.)
If there is only one room, then it is just called "the chapel", if it is divided, the sanctuary is where the altar is, and the nave would be outside the sanctuary where there would be pews, etc. If there is an anteroom, it is called a narthex.
