Langdon is a small town in Sullivan County, New Hampshire, United States. It's a quiet place with a population of 651 people, according to the 2020 census.

History of Langdon

Langdon was first settled in 1773 by a person named Seth Walker. The town officially became a town on January 11, 1787. This process is called incorporation. It was named after Governor John Langdon, who was an important political leader.

One cool thing about Langdon is the Prentiss Bridge. It's the shortest covered bridge in all of New Hampshire! This special bridge was built in 1874. It crosses over a stream called Great Brook. The bridge is a lattice truss type, which means it has a crisscross pattern of wood. It is about 34 feet (10.5 meters) long.

Langdon's Geography

Langdon covers a total area of about 16.3 square miles (42.3 square kilometers). Most of this area is land. Only a tiny part, about 0.08 square miles (0.2 square kilometers), is water. This water makes up less than half a percent of the town's total area.

The town has two main waterways: the Cold River and its smaller branch, Great Brook. All the water in Langdon eventually flows into the Connecticut River. This means Langdon is part of the Connecticut River's watershed, which is an area of land where all the water drains into one main river.

The highest point in Langdon is the top of Holden Hill. It stands about 1,348 feet (411 meters) above sea level.
