Charles River Museum of Industry & Innovation
Machine shop at CRMII wth overhead belt drives.
Charles River Museum of Industry & Innovation houses and displays machinery and artifacts of the American Industrial Revolution from the 19th and 20th centuries. Core exhibits cover the area's role in the Industrial Revolution, though the museum also has a dedicated gallery of the Waltham Watch Company to note the city's watch making history. The museum includes two revolving exhibit spaces that change out anywhere from 3–6 months, covering anything from science and math to cultural investigation. The museum also hosts many events and festivals in the Waltham area, and was the first to host the Watch City Steampunk Festival, which was the first steampunk festival to encompass an entire town.
