This lecture examines some of the many fine historical churches in the Niagara region from the 1830s to the early 20th century. We commence with St Andrew's Presbyterian Church, Niagara-on-the-Lake (1831) and explain Scottish, English and American associations for the 'temple-form' design. After brief consideration of St Vincent-de-Paul Roman Catholic Church, Niagara-on-the-Lake, attention is turned to the Methodist Church at Beaverdams and the reconstruction of its original 1830s design against the background of Meeting Houses. Anglican churches are explored in Port Robinson, Thorold, McNab and All Saints, Niagara Falls. The latter holds a very special place in the history of the Gothic Revival in Canada and even worldwide, being the work of the Scottish architect William Hay who pioneered the recreation of medieval Gothic churches in Canada. The idiosyncratic Anglican Church of St Thomas in St Catharines (1878) by the Buffalo architect Milton Earle Beebe, is investigated against the background of the famous American architect, Henry Hobson Richardson, and in association with the worship of Low Church Anglicans. Holy Rosary Roman Catholic Church, Thorold, by the Dublin-trained architect, Joseph Connolly, is considered against an Irish Gothic background, and we conclude with examination of some Roman Catholic Churches by Connolly's former assistant, Arthur Holmes, in NiagaraFalls, Merritton and St Catharines.
