The Domesday Book (1086) lists eleven or twelve watermills on the River Slea at Sleaford - of which Cogglesford Mill is the only one remaining.  Before the 16th century it was known as Sheriff's Mill and probably dates back into Anglo Saxon times.  The Cogglesford Mill we see today was rebuilt in the mid 18th century and worked until the late 19th, when steam power made it redundant.  The mill gradually decayed until the 1980s when it was restored to full working condition.  It is open to the public from April to September, every day from 12 noon to 4.00pm.  Admission is free.
