Cogglesford Watermill, in East Road, Sleaford, will be open this Sunday, June 10, for a milling day.
The mill, which has been producing flour since the early 1800s, will be open from 11am to 4pm.
Visitors will be able to see the huge water wheels grind the grain to produce wholemeal flour.
There will also be the chance to take home a bag of Cogglesford Watermill’s very own flour on sale in the shop.
