16 Oak Street | 'Where History Meets the River' 16 Oak Street isn't just a home — it's a legacy property. Set on 4.1 private acres with 576 feet of frontage along the Kennebunk River, this estate offers a rare combination of historic significance, complete privacy, and walkability to the heart of Downtown Kennebunkport. Built in 1724, it is one of the town's oldest homes — a remarkable piece of living American history. Inside, original hand-hewn beams, wide plank floors, and preserved period details reflect centuries of craftsmanship, while thoughtful updates provide comfort and function for modern living. The 3-bedroom, 4-bathroom residence is complemented by a detached barn and rolling grounds that include a private family cemetery. This property has the convergence of elements seldom found in one place: true riverfront access, timeless character, in-town convenience, and expansive, secluded acreage. Whether enjoyed as a year-round residence or cherished as a historic retreat, this is a rare opportunity to own something truly irreplaceable.
