Gilbert Clock Factory

The Gilbert Clock Factory is a former production facility in Winchester comprising multiple four-story brick buildings in Second Empire style that line Still River. The structures display characteristic Italianate elements such as ornamental window frames and architectural details visible along Wallens Street.

William Gilbert and Lucius Clarke began clock production at this location in the 1840s, leading to the formal establishment of William L. Gilbert Clock Company in 1871. The facility later became one of New England's major timepiece manufacturers and shaped Winchester's economic development.

The factory was the heart of Winchester's clock industry and shaped both the town's appearance and economic identity for generations. The massive brick structures along the river still reflect the importance this place held for the local community.

The buildings are situated along Still River and accessible from Wallens Street, where the four-story ensemble is visible from various angles. Visitors should note that the structures now serve as residential complexes and cannot be toured inside.

A radioactivity survey conducted in 2018 examined the building for potential contamination from historical radium use in clock hand manufacturing. The results revealed no significant concerns for public health or current residents.
