Betchworth lime quarries To supply the cement for construction associated with required brick built housing, a rich seam of suitable chalk and limestone was identified in the North Downs. Broome Park estate, extending to the top of the hill, included some of these quarries and was integral to the Dorking Grey Stone and Lime Company and the North Downs Line's spur lines leading to these three pits. After an Act authorising the railway from Reading to Reigate was passed in 1847 and its construction, opening in 1849 the Betchworth Quarry Railways were built. To calcinate the lime from the stone, lime kilns were required. The six of the lime kilns along the Pilgrims' Way footpath in Betchworth are Scheduled Ancient Monuments, including Hoffman, Dietz and Six Flare kilns. In 1911 A History of the County of Surrey by Malden which is also a county guide, records the earlier key dates in the industry and records that "the chalk furnishes the chief industry...There are also brickyards in the parish, which is, however, mostly agricultural and residential". Accomplished surgeon to George IV, William IV and Queen Victoria, Sir Benjamin Collins Brodie, lived and died at Broome Park a nursing home since 1993 with 11 acres at the top end of The Street. In 1924 a hydrator plant at Betchworth Limeworks was installed for slaking the lime.
