St Mary of Furness is a Roman Catholic church located on Duke Street in Barrow-in-Furness, England.[1] Designed by English architect E. W. Pugin, the spacious church originally seated 800, but has now been expanded to accommodate around 1,000 worshippers.[1] In 1976 St. Mary of Furness and the church presbytery were granted Grade II listed status by Historic England.[2] The church's organ contains approximately 3,000 pipes and was originally built by Messrs. Hill and Son for the Royal Liverpool Philharmonic Society.[2] The church was placed on Historic England's Heritage at Risk Register as a result of stone decay to the spire.
