It is about 19 miles (31 km) east-south-east of the City of Sheffield and its population is estimated (mid-2004) to be 39,800. It is twinned with the German town Garbsen. Worksop is known as the "Gateway to the Dukeries", so called for the number of ducal residences in the area. Evidence that Worksop existed before the Norman Conquest of England in 1066 is provided by the Domesday Book of 1086: "In Werchesope, (Worksop) Elsi (son of Caschin) had three carucates of land to be taxed. Land to eight ploughs. Roger has one plough in the demesne there, and twenty-two sokemen who hold twelve oxgangs of this land, and twenty-four villanes and eight bordars having twenty-two ploughs, and seven acres of meadow. Wood pasture two miles long, and three quarentens broad."
