History
Falmouth has deep historical roots in Maine, originally settled in the 17th century as part of a larger territory before being incorporated as its own town. The area played a significant role in early colonial New England, and the present-day city of Portland was itself once part of the original Falmouth settlement before separating in 1786. Over the centuries, Falmouth evolved from a community tied to fishing, timber, and agriculture into the prosperous residential suburb it is today.
Did you know?
One little-known fact about Falmouth is that the original Falmouth settlement was among the earliest European communities established in what is now Maine, giving this quiet suburban town a colonial heritage that predates American independence. The town's extensive water area along Casco Bay also makes it a surprisingly rich destination for kayaking, sailing, and coastal wildlife observation, offering residents a slice of true coastal Maine living without the tourist crowds of more famous shoreline towns.
