Chesterfield is a large market town and borough in Derbyshire, England, 24 miles (39 km) north of Derby and 11 miles (18 km) south of Sheffield at the confluence of the River Rother and River Hipper. Including Whittington, Brimington and Staveley, it had a population of 103,801 in 2012, making it Derbyshire's second largest town. It has been traced to a soon-abandoned Roman fort of the 1st century AD. The name of the later Anglo-Saxon village comes from the Old English ceaster (Roman fort) and feld (pasture). Its sizeable street market is held three days a week. The town sits on a coalfield, but little visual evidence of mining remains. Its great landmark is the Church of St Mary and All Saints with a crooked spire.
