Protestant Churches approved cremation gradually after the First World War and the Spanish flu. During the time between the world wars, the development of modern crematoriums also helped to differentiate Christian cremations from Pagan rites of burning the body on a pyre. The first crematorium in Stockholm, Sweden, was built in 1874. In Finland, the Helsinki Lutheran Parish Union built its first modern crematorium in 1926 which is still in use. The first purpose-built crematorium in England was Woking Crematorium, which was built in 1878 and is still in use.
