A chapel is a religious place of fellowship, prayer and worship – most often associated with interfaith worship services. It may be part of a larger structure or complex, such as a church, synagogue, college, hospital, palace, prison or funeral home, located on board a military or commercial ship, or it may be an entirely free-standing building, sometimes with its own grounds. Many military installations have chapels for the use of military personnel, normally under the leadership of a military chaplain. Until the Protestant Reformation, a chapel denoted a place of worship that was either at a secondary location that was not the main responsibility of the local parish priest, or that belonged to a person or institution. Most larger churches had one or more secondary altars, which if they occupied a distinct space, would often be called a chapel. Although chapels frequently refer to Christian places of worship, they are also commonly found in Jewish synagogues and do not necessarily connote a specific denomination. Non-denominational chapels are commonly encountered as part of a non-religious institution such as a hospital, airport, university, prison or military installation. In England, where the Church of England is established by law, nondenominational or inter-faith chapels in such institutions may nonetheless be consecrated by the local Anglican bishop.
