Heritage Open Day: A grade 1 listed building overlooking the beautiful Calderdale town of Todmorden. Come and see our Cappronier stained glass windows, large grounds and other fabulous features. Grade I listed Todmorden Unitarian Church and its surrounding grounds are an arguably unrivalled example of High Victorian Nonconformist Church architecture and Churchyard and an exemplar of the social, economic and cultural impacts of the Industrial Revolution. The Church was built between 1865 and 1869 and designed by John Gibson, an eminent architect who also worked on the Palace of Westminster. The Church is unique in its largely unaltered state, retaining its original Victorian Gothic design and decoration.
