Royal Peculiar

A royal peculiar is a Church of England parish or church exempt from the jurisdiction of the diocese and the province in which it lies and subject to the direct jurisdiction of the monarch.
Definition.
The church parish system dates from Saxon times when most early churches were provided by the lord whose estate land coincided with that of the parish. A donative parish (or "peculiar") was one that was exempt from diocesan jurisdiction. There are several reasons for peculiars but usually they were held by a senior churchman from another district, parish or diocese. It could include the separate or "peculiar" jurisdiction of the monarch, another archbishop, bishop or the dean and chapter of a cathedral (also, the Knights Templar and the Knights Hospitaller). An "archbishop's peculiar" is subject to the direct jurisdiction of an archbishop and a "royal peculiar" is subject to the direct jurisdiction of the monarch.
Most peculiars survived the Reformation but, with the exception of royal peculiars, were finally abolished during the 19th century by various Acts of Parliament and became subject to the jurisdiction of the diocese in which they were, although a few non-royal peculiars still exist. The majority of royal peculiars that remain are situated within the Diocese of London.

The following chapels of the Inns of Court are extra-diocesan, and therefore peculiars, but not Royal:
