This will be an opportunity to both see the chapel itself, located within All Saints Wardour Castle and opened in 1776, and will also include the exhibition of chasubles and copes dating from the 15th to 19th centuries inclusive -- including the 15th century Westminster Chasuble which belonged to Margaret of York, sister of King Edward IV. Moreover, it will also include the exhibition of church plate and an opportunity to view and listen to the chapel's 18th century organ.
