[2] The village is named after Dannemora, Sweden, an iron-making town from where early settlers of this area had emigrated.

Primary and secondary education is provided by the Saranac Central School District.

The early economy was based on mining and smelting iron, but this industry did not become significant until approximately 1843.

After being closed for the mentally ill, this facility was used for a variety of prison programs by the Department of Corrections.

As a result, Dannemora has become a synonym among many in the state for the place where many of its criminally insane are confined.

[4] According to the United States Census Bureau, the village has a total area of 1.2 square miles (3.0 km2), all land.

This means that the portion of the village lying within the town of Dannemora, including the Clinton Correctional Facility, is outside Adirondack Park, while the portion inside the town of Saranac is included in the park.

New York State Route 374, an east-west highway, passes through the village as Cook Street.
