What differentiates "The Hollingsworth House" from its other historic neighbors? The beautiful views to the back and untouched detail for starters. The grandeur is there! 14" foyer ceiling, and 12" ceilings on rest of first floor. Key hole doorways, a stunning winding staircase, original flooring with inlays, seldom seen beechwood wide-plank in some rooms, and six unique fireplaces add to the strong architectural bones. Aesthetic details such as stained glass, crystal chandelier, balcony, and murals will inspire and delight. Large walk-out basement and oversized carriage house provide even more possibilities. Set back off the road, this is an opportunity to enjoy being part of Groton's rich historical Main Street while maintaining some privacy. Buyer to perform due diligence.
