The English architect John Douglas designed 40 new churches. His architectural styles were eclectic, but as he worked during the period of the Gothic Revival much of his output incorporates elements of the English Gothic style. He was also influenced by architectural styles from the mainland of Europe, and frequently included elements of French, German, and Netherlandish architecture. Douglas was born in the Cheshire village of Sandiway and was articled to the Lancaster architect E. G. Paley, later becoming his chief assistant. He established an office in Chester in either 1855 or 1860, from where he practised throughout his career. As his office was in Chester, most of his works were in Cheshire and North Wales, although some were further afield, in Lancashire, Staffordshire, Warwickshire, and Scotland. From an early stage in his career, Douglas attracted commissions from wealthy and powerful patrons. Most of Douglas' new churches have been recognised as listed buildings.
