Redbournbury Mill, originally a water-driven flour mill, lies on the River Ver in the hamlet of Redbournbury between St Albans and Redbourn in the county of Hertfordshire, England.One of its claims to fame is that it was run for much of the 20th century by Ivy Hawkins, claimed to be England's last lady commercial miller. She once tried a repair to the waterwheel by herself, and was trapped when it started to rotate.
