About

Osterville

Osterville, located between Centerville and Cotuit, is a coastal and village-style Barnstable neighborhood with a harborfront setting and a walkable Main Street. The neighborhood’s character concentrates around Main Street at Wianno Avenue, where galleries, outfitters, coffee counters, and small specialty shops set a polished Cape rhythm. Armstrong-Kelley Park frames the village green with lawns and shade trees, while nearby docks and marinas keep salt air in the mix. Shingle-style and Cape Cod cottages sit along shell drives, with larger waterfront homes facing North Bay. The Osterville Historical Society and Museum anchors local history, and the Osterville Village Library adds a quiet civic note. Dowses Beach and Joshua’s Pond shape days around sand, sailing, and freshwater swims.
