From a corporate cocktail party in our historic Parker House, a nautical reunion gathering in our Crosby Boat Shop, or a Hydrangea-filled wedding under a gazebo-styled tent under the summer night sky, the Osterville Historical Museum is the place for you! The museum’s unique 2-acre property is a perfect location to host a private party or wedding. The property can accommodate small parties inside or large ones up to 250 people under a tented area.The tent nestles between the buildings surrounded by a cedar grove. There is also plenty of off-street parking; enough to hold 60 cars.
