The Hospitium Sancti Ioanni Elemosinarii is a charity based in London, England and registered by the Charities Commission, the regulator for charities in England and Wales. The main purpose of the Hospitium is to provide assistance and care for the young and for the elderly. The Hospitium is a confraternity grouping Roman Catholic lay people who promote works of Christian charity and piety following the ethos of the Sovereign Military Order of Malta. It is governed by a constitution and by-laws to follow which every member promises to live by. These rules are not religious vows but rules set up to govern the confraternity. The Hospitium is governed by a Council elected by the confreres for a five-year term and headed by the Almoner (the Chairperson). The confreres of the Hospitium organise the annual May pilgrimage to Lourdes for the disabled. The Hospitium co-operates with a number of charities. In Poland it shares fundraising activities with Foundation of Saint John of Jerusalem.
