Ellenroad Mill is a former cotton‑spinning mill located in the town of Shaw and Crompton, within the Metropolitan Borough of Oldham, Greater Manchester, England. Constructed in 1892, the mill was built for the Ellenroad Cotton Spinning Company and was equipped with state‑of‑the‑art equipment for the production of fine yarns. It featured a five‑storey brick‑clad structure with a prominent octagonal chimney and a large steam engine—an 1800 horsepower horizontal twin tandem compound engine manufactured by William Roberts of Nelson.
The mill operated as a cotton spinning facility throughout the early 20th century, contributing to the region's textile industry. Production declined during the interwar period and the mill eventually ceased commercial operation in 1960. In 1972, the mill was acquired by the National Trust, and in 1990 the Ellenroad Steam Museum was established on the site. The museum preserves the original steam engine, boilers, and ancillary machinery, providing a working demonstration of historic industrial technology.
The Ellenroad Steam Museum is open to the public and is recognized for its well‑preserved engineering heritage. It is listed as a Grade II* building, reflecting its architectural and historic significance. The site also serves as an educational resource, offering guided tours, interpretive displays, and opportunities for visitors to observe the restored steam engine in operation during scheduled demonstration days.
