It was established in 1964 at a large country house in Cross-in-Hand, East Sussex previously known as Possingworth Park, which was renamed as Holy Cross Priory.

[1] Huth built a new country house at Possingworth, designed by Matthew Digby Wyatt at a cost of £60,000, which was completed in 1866.

As built, the new house had several oak-panelled reception rooms, including a large picture gallery for Huth's art collection, 42 bedrooms, and a conservatory.

Its stated objects were “to alleviate need and distress amongst persons of both sexes (especially Roman Catholics) by providing homes, nursing and medical treatment; and to establish, equip, staff and maintain schools for the education of persons of both sexes (especially Roman Catholics)”.
