Five blocks northeast along the river, the Boott Cotton Mills Museum has exhibits that chronicle the rise and fall of the industrial revolution in Lowell, including technological changes, labor movements and immigration. The highlight is a working weave room, with 88 power looms. A special exhibit on Mill Girls & Immigrants (978-970-5000; 40 French St; admission free; 1:30-4:30pm) examines the lives of working people, while other seasonal exhibits are sometimes on display in other historic buildings around town.
