Royal Peculiar (or Royal Peculier) is a place of worship that falls directly under the jurisdiction of the British monarch, rather than under a bishop. The concept dates from Anglo-Saxon times, when a church could ally itself with the monarch and therefore not be subject to the bishop of the area. Later it reflected the relationship between the Norman and Plantagenet kings and the English church. Unlike many of the ecclesiastical foundations of the medieval period the royal peculiars were not abolished in the English Reformation effected under the Tudors.
