Heritage Open Day: The oldest Methodist place of worship in Lincolnshire, built for and dedicated by John Wesley, was constructed by his close friend Robert Carr Brackenbury. Wesley called it 'an earthly paradise'. The chapel's importance to both men may be judged in that the chapel was completed before the magnificent hall next door. Considered by many to be the second most important Methodist building in the world the chapel will be guided by members of the management group who care for it. New guidebook available.
