Southbridge is a city located in the United States, within the state of Massachusetts. The community is locally known by the nickname "The Eye of the Commonwealth" in reference to its historical role in optical manufacturing. The city's current population is generally reported to be on the order of the mid‑to‑high ten thousands.

History

Southbridge has a strong industrial history, shaped largely by the optics trade. For many decades the town hosted American Optical, which was among the leading makers of lenses and optical instruments in the world. Over the later 20th century much production moved out of the area and some operations shifted to locations outside the United States, including Mexico, while the company restructured and changed ownership. The decline of large‑scale local manufacturing had a notable effect on the town but also created opportunities for redevelopment of former factory sites.

Demographics and economy

Southbridge's modern economy is mixed: small manufacturing firms, service businesses, retail, and public‑sector employers all contribute to local employment. The city is often described as a mixing pot of cultures, and it is home to a variety of ethnic groups; community events, churches, and local organizations reflect that diversity.
