Newport
Located around the shores of Lake Sebasticook, Newport first attracted settlers about 1800 and was officially incorporated in 1814. Originally known for abundant fishing and hunting, the lake is the site of an ancient Native American fish weir that predates the pyramids. The settlers who established the town were also industrious and established businesses providing a variety of products, including silk, leather, lumber, and ice. The arrival of the railroad in 1855 further increased local industry and boosted tourism by making the lake accessible to tourists and sportsmen. As fishermen and vacationers alike came to Newport, hotels and camps flourished. The GAR property, Camp Benson, was a popular destination--particularly the Pavilion dance hall. In 1891, a woolen mill and condensed milk plant were built, both of which were vital to the local economy well into the 20th century. In recent decades, Newport has reclaimed some of its natural heritage by making major efforts to restore Lake Sebasticook and the East Branch of the Sebasticook River.
