Greenfield is a village in the civil parish of Saddleworth in the Metropolitan Borough of Oldham, in Greater Manchester, England. It is east of Oldham, and northeast of Manchester. It lies in a broad rural area at the southern edge of the South Pennines. To the east of the village Dovestone Reservoir, Chew Reservoir and Greenfield Reservoir lie in the Peak District National Park. Historically part of the West Riding of Yorkshire, Greenfield is in the Chew Valley, on the main A635 road from Ashton-under-Lyne to Holmfirth. History A Roman road passes along the Saddleworth hills, from the fort of Ardotalia in Glossop to Castleshaw Roman fort. The route of the Roman road passes through Greenfield and crosses Chew Brook at Packhorse Bridge. The old stone houses of Saddleworth date from the 17th century and were home to farmers and hand loom weavers in the woollen trade. The first industrial looms were also designed and built in Saddleworth. England's highest church 'The Heights' and canal tunnel 'Standedge Tunnel' are also here, the latter dating from the end of the 18th century and being a Thomas Telford project. The world's first rock climbers' sit harness was invented in Saddleworth in the 1970s, variations of it now forming the basis of almost all the world's climbing sit harnesses. The poem Jone o Grinfilt was written about a fictional inhabitant of the village with the aim of ridiculing countryside dwellers. The poem was written in the Oldham dialect of English, and was very popular in the 19th century. The author was probably Joseph Lees of Glodwick and it was written in the first decade of the 19th century. In 1849 the Boarshurst Silver Band was formed as the village band. This brass band is still in existence.website Governance Greenfield is in the historic county of Yorkshire and prior to 1974 was administered by the West Riding County Council. In that year governance was transferred to the new Greater Manchester County Council. When that body was abolished in 1986 Greenfield came under the auspices of Oldham Borough Council. Administration under the West Riding County Council led to problems, as Greenfield came under the local administration of Holmfirth for such things as the fire service, despite Holmfirth being significantly further away than Oldham. This was particularly problematic in the winter months, as the roads into the village often become blocked or dangerous due to snow
