There were people living in Nottinghamshire as far back as 40,000 BC, as excavations in the limestone caves at Cresswell Crags (near Worksop) have proved. Much later, when the Romans came, they drove two roads through parts of the county – the Fosse Way to the South, with associated developments at Castle Hill, East Stoke and Brough, and another road to the north, passing near Littleborough. Nottingham itself, however, owes its existence to the Anglo-Saxons, who built the fortified borough of Snotengaham on an easily-defended sandstone outcrop. Fortunately for the future residents of the city, the Normans dropped the 'S' from the name.
