King's Mill was the foremost mill in Wrexham until 1854.

King's Mill, which dates from the 14th century, has a rich and well documented past and is of significant historical importance to Wrexham. Situated at the confluence of the River Gwenfro and River Clywedog, it was the foremost mill in the town until 1854 when the legal requirement for residents of Wrexham to mill grain there was removed. After falling into disrepair, the original mill was rebuilt by Philip Yorke in 1769 King's Mill. The “new” mill continued in use until 1940 when it closed completely due to competition from steam-driven mills in the town. The area fell into decline and by the 1970s the mill was threatened with demolition. In 1973 the area took on a new lease of life when the Erddig estate, including King's Mill, was taken over by the National Trust. The Mill was renovated and opened as a heritage facility by Wrexham Maelor Borough Council in the mid 1990’s but has remained empty since 2012. Canolfan Melin y Brenin is a not for profit community organisation that hopes to lease the building from the Council. The aim is to restore the mill as a self-sufficient community asset which caters for all interests and ages as well as welcoming visitors from outside the community to enjoy the history and heritage of King’s Mill and Wrexham.
