History
Barnstable County — Now
In April 2025, we celebrated National County Government Month with the theme: Barnstable County: Then & Now.
Throughout the month, we highlighted how Barnstable County has evolved over the centuries—from its historic role in the Revolutionary War to the modern-day services that support our communities.
We continue to share these stories, including a special video series featuring Mary LeClair, former County Commissioner (1996–2008) and local history enthusiast. In the first video, she offers fascinating insights into the County’s rich past. You might be surprised to learn about Barnstable County’s role in key moments of early American history—from Revolutionary War connections to pioneering wildfire control with our first airplane in 1954.
Watch the first video in the series below.
Barnstable County — Then
Cape Cod—a narrow, sandy peninsula in southeastern Massachusetts, bounded by Nantucket Sound, Cape Cod Bay, and the Atlantic Ocean—is home to more than 220,000 year-round residents. Its history has been shaped by the waters surrounding it and by the people who have called it home for thousands of years.
Long before the arrival of European settlers, the Wampanoag people, also known as the People of the First Light, lived throughout the region now known as Massachusetts and eastern Rhode Island. This Algonquian-speaking nation has lived here for more than 12,000 years and was part of a rich network of Indigenous nations and communities—many of which continue to thrive today. The Wampanoag people maintain a strong cultural and community presence on Cape Cod to this day.
In 1620, a group of European settlers known as the Pilgrims departed from Plymouth, England, aboard a rented cargo ship called the Mayflower. After a three-month voyage, they first sighted land at the tip of Cape Cod in what is now Provincetown. While anchored there, the adult men aboard signed the Mayflower Compact on November 11, 1620—an agreement establishing a framework for self-government in the New World.
Though they eventually settled in Plymouth, the Pilgrims’ first contact with American soil was here on Cape Cod. On December 21, 1620, an exploratory party landed in the area that would become Plymouth Colony. The territory of the Colony extended from Cape Cod Bay on the east to Narragansett Bay on the west and included parts of present-day Massachusetts and Rhode Island.
The arrival of European settlers marked a significant turning point for the Indigenous peoples of the region—introducing profound and lasting changes to their land, lives, and sovereignty.
Over time, the colonies expanded, and the governance of these growing settlements required more structure. To meet this need, Plymouth Colony created administrative divisions.
Barnstable County was officially established on June 2, 1685, alongside Plymouth and Bristol counties.
At that time, Barnstable County included the following towns:
Sandwich (founded 1639)
Yarmouth (1639)
Eastham (1646)
Barnstable (1650)
After considerable debate, the Town of Barnstable was chosen as the “shire town” or county seat, due to its central location. Barnstable Village became the administrative hub, a designation it still holds today.
Running through Barnstable Village is Route 6A, once known as the Old King’s Highway—one of the oldest traveled roads in the United States.
In its early years, Barnstable County served a judicial role. Over time, its responsibilities expanded to include operating jails, maintaining health facilities, overseeing roads and agricultural land, and managing land and deed records. County government functioned as an administrative arm of the Commonwealth, with officials such as commissioners, treasurers, sheriffs, clerks of court, and registers of deeds elected in accordance with state law.
