Orange Mill Historic District

Orange Mill Historic District is an industrial area in Newburgh containing stone buildings from the 1800s that are now accessible within Algonquin Park. The area includes preserved structures that show how production and landscape were once connected.

The site was founded in 1816 and served for decades as a gunpowder production facility. Its output played an important role during the Civil War, when ammunition was needed for the Union.

The buildings display construction styles from the 1800s that blend craft and industry together. Visitors can observe how stonework and layout reflect the practical needs of former manufacturing operations.

The site sits about 1.5 km northwest of Newburgh along Powder Mill Road and is reached through Algonquin Park. Visitors should wear comfortable shoes since walking over uneven ground and stony areas is required.

This is the only surviving gunpowder production facility from the 1800s in New York and preserves a rare industrial craft tradition. Several of the stone structures lack roofs, showing how time and nature have reclaimed this old factory.
