Warner is a town in Merrimack County, New Hampshire, United States. The population was 2,833 at the 2010 census. The town is home to Magdalen College of the Liberal Arts, Rollins State Park and Mount Kearsarge State Forest.
The town's central settlement, where 444 people resided at the 2010 census, is defined as the Warner census-designated place (CDP), and is located along New Hampshire Route 103 and the Warner River. The town also includes the villages of Davisville, Lower Village, Melvin Mills, and Waterloo.
The town was granted in 1735 as "Number One" by Massachusetts Governor Jonathan Belcher to petitioners largely from Amesbury, Massachusetts. Called "New Amesbury", it was part of a line of settlements running between the Merrimack and Connecticut rivers intended to help defend Massachusetts against New France's predations. It was regranted by the Masonian Proprietors in 1749, when it was settled with four houses and a sawmill. Called "Jennesstown", it was abandoned and destroyed during the French and Indian War. The town was granted again in 1767 to Jonathan Barnard and others, who called it "Amesbury". But on September 3, 1774, it was incorporated as "Warner", named after Jonathan Warner, a leading Portsmouth citizen, namesake of the Warner House and relative of Governor John Wentworth. It was one of the last towns established under English provincial rule prior to the Revolution.
Warner developed into a prosperous farming community which produced meats, dairy goods, vegetables, hay and apples. The Warner River and its tributaries provided water power for mills, which in 1832 included twelve sawmills, 6 gristmills, a paper mill and two clothing factories. By 1858, there was also a cabinet manufacturer and bottle manufacturer. In 1885, industries included a bedstead factory, chain factory, woolen cloth factory, iron foundry, tannery and glove manufacturer. On September 9, 1821, the town was hit by a tornado. It leveled houses and forests in a 16-to-18-mile (26 to 29 km) swath of destruction beginning west of Lake Sunapee, through New London and Sutton, over the southwest spur of Mount Kearsarge and ending at the Webster line. The storm killed four people in Warner, seriously injured others and destroyed considerable property.
According to the United States Census Bureau, the town has a total area of 55.9 square miles (144.8 km2), of which 55.7 sq mi (144.3 km2) is land and 0.2 sq mi (0.5 km2) is water, comprising 0.43% of the town. Warner is drained by the Lane and Warner rivers. Two covered bridges span the Warner River: the Dalton Bridge and the Waterloo Bridge.
Mount Kearsarge, elevation 2,937 feet (895 m) above sea level, located in the extreme north of the town, is the highest point in Warner. Two state parks are located on the mountain: Rollins State Park in Warner and Winslow State Park in Wilmot. Mount Kearsarge is a popular hiking destination, due both to its bare, rocky summit, and to the fact that a paved road climbs from Rollins State Park to within a half mile of the summit. The peak is the highest point along the 75-mile (121 km) Sunapee-Ragged-Kearsarge Greenway, a hiking trail which links 10 towns and encircles the Lake Sunapee region of western New Hampshire.
The town is served by Interstate 89 and New Hampshire Route 103. State routes 114 and 127 cross the extreme southwestern and southeastern corners of the town, respectively. It borders the towns of Wilmot, Andover and Salisbury to the north, Webster to the east, Hopkinton and Henniker to the south, Bradford to the west, and Sutton to the northwest.
