Sleaford

The first settlement formed in the Iron Age where a prehistoric track crossed the River Slea. It was likely home to a mint for the Corieltauvi in the 1st centuries BC and AD. Evidence of Roman and Anglo-Saxon settlement has been found. Medieval records differentiate between Old and New Sleaford, the latter emerging by the 12th century around the present-day market place and St Denys' Church; Sleaford Castle was also built at that time for the Bishops of Lincoln, who owned the manor. Granted the right to hold a market in the mid-12th century, New Sleaford developed into a market town and became locally important in the wool trade, while Old Sleaford (based near the site of the prehistoric settlement) declined.
