The Challoner Hall is named after one of the towering figures of English Catholicism: Bishop Richard Challoner (1691 – 1781), Vicar-Apostolic of the London District during the anti-Catholic Gordon riots of 1780. Often in frail health, he was forced to spend much of his life in hiding and frequently changed address to avoid capture. A prolific writer and tireless apologist for the Catholic faith, one of his most famous works was a prayer book for the laity, the Garden of the Soul, published in 1740. He would have know Warwick Street chapel well.

The Hall, at 24 Golden Square, was extensively refurbished in 2016 and was re-opened and blessed on 6th January 2017 by the then Apostolic Nuncio, H.E. Antonio Mennini. It is an ideal space, with fully equipped kitchen, for gatherings of up to 70 people and is available for hire.
