Winnekenni Castle in Haverhill, Massachusetts overlooks Kenoza Lake and sits on expansive grounds featuring trails, a basin, and round pond. Though the castle building itself is currently closed by the city due to the need for extensive rehabilitation and renovation, the property remains managed by the City of Haverhill and continues to serve as a venue for special events on its picturesque grounds. The Winnekenni Foundation has supported preservation efforts since 1968, maintaining the landmark's cultural importance to the region.
