Located two miles southwest of Milford, Abbott’s Mill was added to the National Registry of Historic Places on May 18, 1979. The site was established as a sawmill in 1795 and converted to a gristmill after 1808. The site remains named after Ainsworth Abbott who purchased it in 1919.
The current two and a half story building is a later 19th century structure, built on what is thought to be the original mill building’s foundation, with extensive renovations from the late 1800’s and an addition from the early 1900’s. The machinery and chutes from the original mill that remain on the site were used to process grain, reflecting Delaware’s rich past as an agricultural center.
Constructed almost entirely of wooden frame, the building became vulnerable to several factors including age, water infiltration, insect damage and its proximity to a road. Damage to the beams and framing meant that Abbott’s Mill needed to be closed to the public for reasons of safety.
The Division for Historical and Cultural Affairs (HCA) will begin restoration and repair of the structural framing at this historic landmark this summer. Out of concern for public safety and to ensure that the site will reopen with no lingering effects of damage, a structural engineer was brought in to assess the site as well as an architect to plan out every step of repairing the space. A thorough engineering study and design was completed, and work is set to begin with an eye towards reopening the site for interpretive programming by the Delaware Nature Society who lease the space and who facilitate workshops, exhibits, walking trails along the property, school trips and other programs.
