At Frogmore Paper Mill, we celebrate the huge contribution that paper has played in shaping the world in which we live today. In 1803 Frogmore Paper Mill was the place selected by Henry and Sealy Fourdrinier for the trials of their newly patented paper machine. Thus began the paper's industrial revolution, leading to the cheap, plentiful paper products that we all use every day of our lives. Frogmore is still a working paper mill and, today, is operated by the Apsley Paper Trail, a charitable trust founded to conserve the unique industrial heritage of this site in Hemel Hempstead. It is also a visitor, education and community use centre as well. The trust is entirely self-financing, with all proceeds from its activities being re-invested in the repair, maintenance and development of the mill and its historic equipment. Group visits can be arranged on Mondays, Tuesdays, Wednesdays and Fridays, leaving Thursdays free for drop-in visitors. If the group is sufficiently large (30+), a weekend visit may be possible. After an introductory presentation, we typically subdivide larger groups into parties of 12 with each party doing a different activity at the same time. Everyone gets to do everything, just in a different order. Our ideal party size is 12 so we are quite used to welcoming groups of 24, 36, 48 or even larger. For groups that wish to include a meal in their visit, we can arrange for a fish and chip lunch, or delicatessen prepared buffet, to be delivered to our premises. Both are very popular.
