Linchester Mill

Linchester Mill is a historic grist mill located at Preston in Caroline County, Maryland, United States. The original mill was built at the site in about 1682; the current structure was erected in approximately 1840 and is a $2 1/2$-story frame building sided in red-painted weatherboard and roofed with raised-seam metal. It is four bays long and two bays deep, with a two-story lean-to addition. Then known as Langrell's Mill, operations ceased in 1974 but currently houses a museum collection of milling machinery dating from the 19th century to the mid-20th century.

It was listed on the National Register of Historic Places in 2009 after renovations began in 2004.
