Howsham Mill sits on a small island in the River Derwent near Malton in North Yorkshire. It was built in 1755 to impress, an eye-catcher, by the new heir to the Howsham Estate. It served the farmers of the area until its closure in 1947, grinding corn for both flour and livestock feed. The building fell into disrepair as the woodland grew up around it. A chance discovery in 2003 resulted in the formation of the Renewable Heritage Trust and a project to restore this beautiful mock-Gothic building, to give it a new lease of life fit for the 21st century. The waterwheel and two Archimedes Screw turbines now generate hydro-electricity and the mill is an education centre. This is its story.
