Dead rats aside, there was one area of the garden that always made me feel a little uneasy. As the name suggests, there was once a mill here. Upper Vatch Mill was one of several in the area and reputedly the highest around Stroud, at seven storeys. In the late 18th century it was a paper mill, but by the 1820s had become a cloth-mill. By the end of the Victorian era, the mill was gone.
