Although the terms gristmill or corn mill can refer to any mill that grinds grain, the terms were used historically for a local mill where farmers brought their own grain and received back ground meal or flour, minus a percentage called the miller's toll..
Some people took advantage of this right and became full-time millers. At the mills, neighbouring peasants paid a fee to have their grain ground. Sometimes, a few peasants built a mill together and took turns in using it. In the Middle Ages, a lot of land was owned by the Church or the nobility. A mill could not be built on their land without special permission.
