Limestone has been extensively quarried at various times on either side of Golvers Hill at Rydon, Coombesend and Gildons. Kingsteignton Quarry at Rydon (now infilled) supplied stone for the building of Buckfast Abbey. Numerous limekilns, some still in existence, were found along the dry valley that extends from Rydon to Lindridge and along the Coombesend valley. The kiln at Kiln Forehead was demolished during the extension of Calvados Park whilst the kiln beside Rydon school was partly demolished and buried under an earth bank when the lane to Rydon Quarry was widened.
