The white clapboard Osborn Cannonball House is a small jewel in the center of Scotch Plains. Brick walks, an arbor and formal gardens surrounded by a white board fence give this property a “Williamsburg” feel. Its location, adjacent to the town green and across from the Stage House Inn, adds to its interest. Inside, four furnished rooms appointed with colonial and early 19th century furnishings will delight the visitor. A parlor reflects Victorian tastes. Built in the 1700s by Jonathan and Abigail Osborn, the house takes its name from the cannonball that struck it during a Revolutionary War skirmish.
