Middlesex County, Massachusetts

Middlesex County lies just north of Boston. It’s the most populous county in Massachusetts, stretching from the suburbs of the capital to the quiet towns along the New Hampshire border.
Lowell was once a powerhouse of the Industrial Revolution. Now, it has reinvented itself as a cultural hub. Cambridge, home to Harvard and MIT, pulses with intellectual energy.
You’ll find revolutionary war sites scattered throughout. This helps remind visitors of the area’s role in shaping the nation. The county’s diversity shines through its food scene. Despite its size and variety, Middlesex County maintains a strong sense of community. It still is a cornerstone of local governance in many places.
