The Nashoba Brook Stone Chamber is an underground stone structure in the woods of the Nashoba Brook Conservation Area of Acton, Massachusetts. Its more common name is the "potato cave", which comes from the traditional assumption that it was once used as a root cellar.

Some argue that it may originally have been a pre-colonial native American ceremonial stone landscape structure. Local lore states that it also served as shelter for workers on the nearby railroad in the 19th century.

Middlesex County is located in the Commonwealth of Massachusetts, in the United States. As of the 2020 census, the population was 1,632,002, making it the most populous county in both Massachusetts and New England and the 22nd most populous county in the United States.

On July 11, 1997, Massachusetts abolished the executive government of Middlesex County primarily due to the county's insolvency. Middlesex County continues to exist as a geographic boundary and is used primarily as district jurisdictions within the court system and for other administrative purposes; for example, as an election district.
