Industrial School for Girls exhibit

The Commonwealth Museum in the Massachusetts Archives building at Columbia Point is displaying “An Extraordinary Look into Ordinary Lives: Uncovering Dorchester’s Industrial School for Girls, 1859-1880” now through July.

History and archaeology combine to tell the story of Dorchester’s Industrial School for Girls, a 19th century “child-saving” institution, and those who walked its halls. The middle and upper class managers of the school trained these young girls in the domestic arts and proper female virtue in hopes that they would become productive members of the working class.

Using school records and artifacts uncovered during a 2015 archaeological dig, the Commonwealth Museum’s new lobby exhibit brings this never-before-told story of Victorian moral reform to life. The girls’ individual experiences at and after the school take center stage, but the exhibit also explores class dynamics, gender roles, race relations, sickness and disease and leisure in 19th century Boston.

Further information can be found at www.sec.state.ma.us/events or by calling 617-727-9268.
