The Brookeville Woolen Mill is home to the spirit Lily Lilac, star of many a newspaper article at Halloween. Lily was so named because she left the scent of lilacs whenever she appeared as well as the occasional lip prints on mirrors and windows .
The Brookeville Woolen Mill is actually the miller’s house, the mill being just down the hill from the house (you can see a glimpse of it through the trees in the picture above). The buildings date to the late 1700s and were a fulling mill and woolen factory. Many people don’t realize that Montgomery County had a lot of manufacturing in small mills. The county’s geologic composition means that there are a lot of healthy streams throughout the county (as evidenced by our current stream valley park system) creating ample water power – ideal for mills. The Brookeville area had many mills, including a mill town, Triadelphia.
Evidence of this mill heritage remains in the many mill road names found throughout the county. Some of the mill buildings, like the Brookeville Woolen Mill, have found new life as homes and businesses (the Hyattstown Mill may be the only mill space used for public programs in the county) and the ruins of many mills can be found in county parks (Black Rock Mill is a good example). To see what an operating mill is like, the Pierce Mill in Rock Creek Park (once part of Montgomery County) is a functioning grist mill and living museum.
