Overview of Dover and it's history

Discover Dover, NH: A Blend of History and Charm

Nestled along the banks of the Cocheco River, Dover, New Hampshire, brims with small-town allure and a rich tapestry of American history. Founded in 1623, Dover holds the distinction of being the oldest continuous settlement in New Hampshire and the seventh oldest in the United States. As a cornerstone of the New England region, Dover rapidly evolved from a fishing and trading hub into a bustling industrial center, thanks to the robust water power offered by the falls.

Entrepreneurs and Industry

Throughout its history, Dover has been home to industrious souls whose ingenuity left an indelible mark on the local and national economy. Notably, Dover-native Elisha Otis revolutionized the way we navigate urban landscapes by inventing the safety elevator in the 1850s. This invention not only made skyscrapers a viable option but also cemented Otis' name as a titan of industrial safety and innovation. Entrepreneurs in textiles and shoe manufacturing also capitalized on Dover's resources, further shaping the economic landscape of the city.

Dover thrived in the 19th century with industries such as the historic Sawyer Woolen Mills and the Cocheco Manufacturing Company, which made Dover a hotbed for the cotton industry. Today, remnants of such entrepreneurial spirit linger, with businesses in technology and education reflecting Dover's ongoing commitment to progress and prosperity.

Landmarks and Leisure

Dover's commitment to preserving its heritage is exemplified by an array of historic sites and recreational destinations that continue to draw visitors and residents alike. The Woodman Institute Museum, a beacon of local history, art, and natural science, offers a glimpse into Dover's past through its exhibits and preserved colonial-era buildings. The ornate architectural features of historic homes like the Hale House and the William Damm Garrison celebrate Dover's colonial roots, and they stand as testament to centuries-old craftsmanship.

For outdoor enthusiasts, Dover boasts a variety of parks and recreational areas. The Bellamy River Wildlife Sanctuary offers a serene setting for birdwatching and hiking, whereas Hilton Park at Dover Point provides spectacular views of the Piscataqua River with picnic and fishing amenities. Garrison Hill Park, known for its iconic observation tower, allows panoramic views of Seacoast New Hampshire, adding a touch of natural splendor to the historical wonders of Dover.

As the gateway to the scenic Seacoast region, Dover, NH, wonderfully melds its historical heritage with modern vitality, offering a unique experience for those who choose to explore its streets, stories, and scenic beauty.
