New London’s 10th annual Old Town Mill Harvest Festival will be held from 11 a.m. to 3 p.m. Saturday, Oct. 19, featuring free horse-drawn wagon rides, craft vendors, music, kettle korn, apple cider and doughnuts.

The grist mill at 8 Mill St. will be open for tours and the showing of a video on mill operations. The Old Town Mill originally was built in 1650 by John Winthrop Jr., the founder of New London and later the governor of Connecticut.

Listed on the National Historic Register, the mill is one of the oldest industrial sites in Connecticut, but on Sept. 6, 1781, General Benedict Arnold burned the mill down during his raid on New London. The mill was rebuilt soon after on the original site, and it retains much of its original charm.

The Old Town Mill grounds are open year round until sunset. The mill is also available to groups at arranged times by contacting Judi Cox at (860) 447-5243.
