The Promise Chalice and paten was a gift sent to Londonderry in 1613 by the Honourable The Irish Society. The gift represented a promise to build a cathedral for the people of the city. The chalice is still used today for special Holy communion services at St Columb's Cathedral. In our design the gilt and silver chalice and paten are set against a background of bright colour suggesting stained glass windows. The Cathedral's battlements are referenced as a border to the design.
