Green Hammerton is a village and civil parish in the Harrogate district of North Yorkshire, England.[2] (H)ambretone, a place-name reflected now both in Kirk Hammerton ('Hammerton with the church', from Old Norse kirkja 'church') and in Green Hammerton ('Hammerton with the green', from Middle English grene), is first attested in the Domesday Book of 1086.[3] The name seems to derive from the Old English plant-name hamor (whose meaning is not certain but might include hammer-sedge or pellitory of the wall) + tūn 'settlement, farm, estate'.[5] The former Congregational church in Green Hammerton, originally built as a Methodist Chapel in the late 1790s, was adapted for use as a Roman Catholic Church, St Josephs, in 1961.[8] Green Hammerton comes under the Ouseburn ward, of Harrogate District Council, the Ainsty division of North Yorkshire County Council and the Selby and Ainsty parliamentary constituency.
