Blankney lies between Metheringham and Scopwick beside the B1188 on the edge of Lincoln Heath. To the east the limestone dip slope gradually declines until at Car Dyke it meets the Witham peat fens.
Blankney village is at the centre of a large estate originally granted to Walter De Aincourt by William the Conqueror for service rendered at the Battle of Hastings. It remained the principal family seat for 400 years until in 1466, it passed by marriage into the hands of the Lovell family.
After the War of the Roses, the estate was purchased by the Thorolds and it passed, again by marriage, into the hands of the Widdrington family during the reign of Charles I. It was acquired by the Chaplin family in 1719 who held it until 1892 when it was sold to cover debts to the Earl of Londesborough. The 2nd Earl built the first Blankney golf course in 1909.
Though St Oswald's Church and the hall (demolished in 1965 after a tragic wartime fire) are older, the 'modern' estate village with its picturesque limestone cottages, golf club and cricket ground is largely the creation of the Chaplin family.
