Charles Manners-Sutton was Archbishop of Canterbury when Addington was acquired in 1807 for the use of the see. The purchase transformed the former Addington manor-house estate into an archiepiscopal country residence.

The holding is recorded institutionally in the name of the Church of England and the see's trustees, not as the personal freehold of the archbishop.
