Central to any farm or grange (estate farm without a farm house) were barns, often the largest one would be known as the main barn. One of the most common rural buildings was the threshing barn, where raw materials would be threshed to separate the grain and straw with the straw kept in the barn for animal bedding to be used in the stables or ox/cow sheds. Other harvest produce like root crops would also have been kept in a barn. This barn also has a lean-too shed attached where the farm workers could store their tools and the like especially if this barn was some distance away from the main farm, having a securable shed on site was often very helpful.
