Cantley Hall is a grade II* listed Georgian mansion set in 400 acres (160 ha), in the village of Old Cantley in Doncaster, South Yorkshire, England.
It is constructed in two storeys of stuccoed brick with a graduated Westmorland slate roof.
Cantley Hall was probably a home from around the 7th or 8th century, owned by a Saxon called Tochi prior to the conquest of England by the Normans in 1066, after which it probably went to the Everingham's or Everingham Ancestors. By 1209 it was known as Kanteleia, and Cauntele in 1246. By 1280 it was in the possession of Robert de Everingham. By the late 15th century the name of Cantley had been established and remained, while the residents of the estate were the Smith family.
In 1610, Hugh Childers the Mayor of Doncaster from 1604, added Cantley Lodge to the existing family's traditional home at Carr House, Warmsworth, Doncaster by buying the Cantley estate from the Stapleton family. In 1714 Leonard Childers of Cantley Lodge bred the famous stallion "Flying Childers", son of "Darley Arabian". "Flying Childers" was later sold to the Duke of Devonshire, was never beaten and is still regarded as one of the fastest horses ever raced. He later retired to Chatsworth House, Derbyshire although he mainly covered mares owned by the Duke, as he was too far away from the main breeding centre of Yorkshire.
Leonard's successors after his death in 1748 were his daughter Mildred Childers, who had married William Walbanke, and then their son Childers, who probably moved from Carr House to Cantley later in the century and who added the surname Childers to his own on inheriting. Between 1785 and 1786, Childers Walbank Childers considerably remodelled Cantley Lodge into an impressive country mansion and created the shooting forest Black Carr Plantation.
