Chapel
A chapel is a Christian place of prayer and worship that is usually relatively small.
In Roman Catholic Church canon law, a chapel, technically called an "oratory", is a building or part thereof dedicated to the celebration of services, particularly the Mass, which is not a parish church. This may be a private chapel, for the use of one person or a select group (a bishop's private chapel, or the chapel of a convent, for instance); a semi-public oratory, which is partially available to the general public (a seminary chapel that welcomes visitors to services, for instance); or a public oratory (for instance, a hospital or university chapel).
