Walpole is a town in Norfolk County, Massachusetts, United States. It is located about 17.9 miles (28.8 km) south of Boston and 23.5 miles (37.8 km) north of Providence, Rhode Island. The population was 24,070 at the 2010 census. Walpole was first settled in 1659 and was considered a part of Dedham until officially incorporated in 1724. The town was named after Sir Robert Walpole, de facto first Prime Minister of Great Britain. After the territory was bought from Dedham, the saw mill industry began to rise in the area. The first saw mill in Walpole was built near what is now School Meadow Brook and the Neponset River. It was located in the area that is now the Walpole Town Forest. The mill was built and later owned by Joshua Fisher and Major Eleazer Lusher, two wealthy men of Dedham.
