Grinton Smelt Mill

Grinton Smelt Mill (or How Mill) in Swaledale, North Yorkshire. This ruined lead mining and processing site on Cogden Moor was built c1820 to process lead won by hushing and hydraulic mining. The buildings and 300 metre long stone flue leading up to Sharrow Hill are grade II* listed structures and scheduled monuments. The site is recognised as being the best preserved lead mining site in the Yorkshire Dales...A mill had existed on the site since the early 18th century, but the later addition of a 980-foot (300 m) flue allowed workers to recover waste lead from the flue.
