What stands out about Swanzey’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
First granted in 1733 as "Lower Ashuelot", Swanzey was one of the fort towns established by Governor Jonathan Belcher of Massachusetts, which then claimed the territory. The town was the site of many battles during King George's War, and in 1747 it was abandoned for three years. It was regranted to 62 proprietors on July 2, 1753, by Governor Benning Wentworth as "Swanzey", most probably because some early settlers had a connection to Swansea in Wales. Situated on the Ashuelot River and connected by the Ashuelot Railroad, West Swanzey developed as a textile mill town, and East Swanzey produced wooden buckets for generations. By 1859, the population was 2,106.
