Nidderdale Marble is a variety of crinoidal limestone, a distinctive stone used in decorative work in the churches and abbeys of northern England. Fountains Abbey and the neighbouring Fountains Hall are the only known buildings where Nidderdale Marble was used. This book describes the locations within the Abbey complex where the marble was used and relates that to the chronology of construction. A quarry at Lofthouse, in Nidderdale, is suggested as the most likely source.
