Built around 1720, the Cammett House is one of the oldest surviving homes in Osterville, Cape Cod, offering a rare and authentic look at early colonial architecture. Named for the family of John Cammett, who married in 1808 and is the earliest known resident, this historic home features a classic post-and-beam, one-room-deep design with an ell and extension added in the 1830s.

Visitors can explore the house’s original construction techniques through a lower-level observatory that reveals the exposed underpinnings of the 18th-century structure—making it a fascinating stop for architecture and history enthusiasts alike.

Outside, a 1700s-style herb garden, designed and maintained by the Osterville Garden Club, features traditional culinary and medicinal plants commonly used by early settlers. Inside, the colonial kitchen includes a beehive oven, root cellar, and authentic 18th-century cooking tools, giving guests a hands-on look at daily life in early New England.
