Est. 1908 · Major 19th-century cotton mill complex (Cocheco Manufacturing Company) · Site of the deadly January 26, 1907 Mill No. 1 fire (four fatalities) · Restored mixed-use industrial heritage landmark in downtown Dover
Dover's mills trace to 1812, when John Williams and fellow investors formed the Dover Cotton Factory on the Cocheco (originally 'Cochecho') River. The enterprise became the Dover Manufacturing Company in 1823 and later spun off the Cocheco Manufacturing Company; a clerical error by the state recording the name produced the 'Cocheco' spelling that endures. At its peak the five-story Cocheco Manufacturing Company employed more than 600 workers.
The complex's defining tragedy came on January 26, 1907. With the sprinkler system on the third, fourth, and fifth floors shut off for repairs, a wet but operating leather belt slipped, struck a belt box, and threw sparks into nearby cotton. The fire spread rapidly through Mill No. 1; power was cut, leaving workers to flee through darkness and smoke. The building had only one fire escape, and many workers were injured leaping from windows. Firefighters battled the blaze for thirty-six hours in temperatures near thirty degrees below zero, with water freezing almost instantly. Four lives were lost.
Mill No. 1 was rebuilt in 1908, reportedly reusing portions of the surviving structure. The Cocheco Mills complex was later known as the Clarostat Building and as One Washington Center.
Today the buildings, owned and restored by Chinburg Properties, form the Washington Street Mills / Cocheco Mills, a mixed-use complex at 1 Washington Street in downtown Dover combining offices, artist studios, and 54 residential apartments completed in December 2018. The Cocheco Mills district stands as one of the most significant surviving industrial complexes in New Hampshire's Seacoast region.

The Dover Mills' haunted reputation is tied directly to the workers who died in the 1907 fire. According to local reporting, including a feature in The Yankee Express, people who have spent time in the complex after hours describe strange lights appearing in higher-level rooms, the unmistakable sound of machinery turning on and off, and disembodied voices echoing through buildings that should be empty.
One persistent account, originating in the Shadowlands submission and echoed in later coverage, describes a single light that remains on in a sealed-off basement no one enters, along with faint, unidentifiable noises heard by anyone sitting alone on the tower stairs. While these specific details trace to anonymous and informal sources, the broader paranormal tradition around the mills is independently noted in regional media and local ghost lore, consistently framed around the tragedy of the 1907 fire and the workers who lost their lives there.
The combination of a documented mass-casualty industrial fire and a labyrinthine 19th-century mill complex has kept the Dover Mills a fixture of Seacoast New Hampshire ghost stories for generations.
