Overview of Dover and it's history

Discover Dover, Massachusetts: A Blend of History and Harmonious Living

Nestled in the lush landscape of Norfolk County, Dover, Massachusetts is a small town that prides itself on preserving its rich history while fostering a serene, community-driven lifestyle. Established in 1836, Dover started as an agricultural town and evolved with the times while retaining its quintessential New England charm.

A Storied Past: Dover's Historical Milestones

Dover's origins can be traced back to its early settler days when it was part of Dedham, known as the Springfield Parish. It was during the 18th century that Dover began to carve out its identity, with the construction of the oldest surviving house in town, the Benjamin Caryl House — built in 1777 for its namesake, Dover's first minister. Throughout the years, Dover has been home to mills and small factories, benefitting from the waterpower that the Charles River provided.

As the industrial revolution took hold, Dover transitioned towards a more residential character. Its pastoral appeal attracted notable residents, including a number of Boston's elite who sought a rural retreat from city life. The town's commitment to conservation and open space has ensured that much of its bucolic landscape remains untouched, offering a glimpse into the town's pastoral past.

Notable Entrepreneurs and Dover's Claims to Fame

Dover may be small, but it has been the home of several entrepreneurs and public figures, adding to its quiet allure. One famous entrepreneur who once called Dover home was Sheldon Adelson, a business magnate known for his vast casino and hospitality empire. His legacy as a philanthropist and influential political donor started from humble beginnings before reaching global heights.

The town is also recognized for the Dover Demon, a creature of urban legend that captured the imaginations of cryptozoologists worldwide after supposed sightings in the 1970s. While evidence of the creature's existence is purely anecdotal, the story remains a curious footnote in Dover's cultural history.

Explore and Enjoy: Historic Places and Recreation Spots

Dover offers a range of historical and recreational spots that cater to those seeking to immerse themselves in the town's heritage or enjoy its natural beauty.

  • The Benjamin Caryl House and the adjacent Sawin Building provide a fascinating glimpse into 18th and 19th-century life, showcasing period artifacts and exhibits.
  • The Charles River offers serene settings for kayaking and fishing, embraced by conservation lands and walking trails.
  • Noanet Woodlands is a favorite destination for hikers and nature lovers, with trails leading to the summit of Noanet Peak, where one can view the Boston skyline.
  • Powisset Farm, part of the Trustees of Reservations, is not just a working farm but also a testament to the region's agricultural roots with a robust calendar of community events.

Dover's commitment to preservation and community shines through in its well-maintained trails, protected landscapes, and carefully curated historical sites. It's a town where the echoes of the past meet the mindful stewardship of the present, creating an inviting atmosphere for residents and visitors alike.
