Priory is a simple incense, pure frankincense with no additional oils. Frankincense, or gum olibanum, comes from South Arabia and the Horn of Africa, and has been used as the basis of incense for several thousand years.

The Benedictine Monks of Prinknash Abbey have been blending incense since 1906, when the community was on Caldey Island and are now the oldest major incense blenders in Europe.
