Britain's Polish immigrants tended to settle in areas near Polish churches and food outlets. In West London, they settled in Earl's Court, known in the 1950s as the "Polish Corridor", in reference to the interwar Central European political entity and, as house prices rose, they moved to Hammersmith, then Ealing, and in South London, to Lewisham and Balham. As these communities grew, even if many Poles had integrated with local British educational and religious institutions, the Polish Catholic Mission in England and Wales, in agreement with the English and Scottish hierarchies, considered that Polish priests should minister to Polish parishioners. The original Polish church in London in Devonia Road, Islington was bought in 1928 with much delay, following the First World War. However canonically, subsequent Polish "parishes" are actually branches of the Polish Catholic Mission and not parishes in the conventional sense and are accountable to the episcopate in Poland, through a vicar delegate, although each is located in a British Catholic diocese, to whom it owes the courtesy of being connected. The first post-war Polish "parish" in London was attached to Brompton Oratory in South Kensington, followed by a chapel in Willesden staffed by Polish Jesuits. Brockley-Lewisham was founded in 1951, followed by Clapham, while St Andrew Bobola church in Shepherd's Bush (1962) was regarded as the "Polish garrison" church. Among its many commemorative plaques is one to a clairvoyant and healer housewife and Soviet deportee, Waleria Sikorzyna: she had had a detailed premonitory dream two years before the 1939 invasion of Poland, but was politely dismissed by the Polish military authorities. Currently the Polish Catholic Mission operates around 219 parishes and pastoral centres with 114 priests throughout England and Wales. In 2007 Cardinal Cormac Murphy-O'Connor, primate of England, expressed concern "that Poles are creating a separate Church in Britain", but Polish rector, Mgr Kukla, responded that the Polish Catholic Mission continued to have a "good relationship" with the hierarchy in England and Wales and said that integration was a long process.
