The Osterville Historical Museum, established in 1931, preserves the history of Osterville for all of those who love her, past, present, and future. The museum includes the largest collection of wooden boats in Massachusetts and is home to the Crosby Boats. The Crosbys are America's oldest, currently active, wooden boat building family. The Cammett House, the oldest house in Osterville, and the Captain Jonathan Parker House, owned by a 1820s coastal schooner captain, are also located on the museum campus. A series of boat shops includes the 1850 original Herbert F. Crosby boat shop. Every Friday mid-June to mid-September, the museum hosts the Osterville Farmers' Market.
