It’s easy to miss St Lewis’ Church in Croft, Warrington. Tucked behind the presbytery, the red-brick chapel is deliberately modest. When it was built in 1827 – the period between the Roman Catholic Relief Act of 1791 and Catholic Emancipation Act of 1829 – there was no question of it having bells or a steeple. It was for agricultural workers and weavers, the poor believers of an unfashionable faith, in a sliver of villages between two great industrial cities: Liverpool and Manchester.
