Nashoba Brook Pencil Factory Site

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. Research and excavation from 2006 supports this assertion, finding evidence of construction from the 18th or 19th century for the purpose of storing food. 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.

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. Middlesex County is one of two U.S. counties (along with Santa Clara County, California) to be amongst the top 25 counties with the highest household income and the 25 most populated counties. It is included in the Census Bureau's Boston–Cambridge–Newton, MA–NH Metropolitan Statistical Area. As part of the 2020 United States census, the Commonwealth's mean center of population for that year was geo-centered in Middlesex County, in the town of Natick (this is not to be confused with the geographic center of Massachusetts, which is in Rutland, Worcester County). 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.
