Listen: Howsham Mill from above - 'children love standing on top of the water wheel'published at 13:29 British Summer Time 7 June 2017
Do you remember Howsham Mill on the River Derwent in Ryedale?
The Grade II-listed 18th Century mill was a finalist on the 2006 BBC Two series Restoration Village.
Work to rescue the mill, overseen by the Renewable Heritage Trust, began in 2004.
It now supplies energy to the National Grid and children can go there to learn about it.
I've been to meet the team that runs it and bumped into Trustee, Valerie Hood, who says the mill, on an island in the middle of the Derwent, is "a magical place for children to visit"
