Bissett, Rachel E.Founded in 1847 in Baltimore, Maryland, by the School Sisters of Notre Dame (SSND), the Institute of Notre Dame (IND) was a pioneering all-girls Catholic high school that provided educational opportunities to women for 173 years. Built as a convent school in a 19th-century classical revival style starting in 1863, the building expanded six times, creating one building of roughly 200,000 square feet that reflects its growth and adaptation to educational and religious needs. Unlike many historic Catholic high schools that relocated during Baltimore’s demographic shifts, IND remained committed to its community in the Oldtown neighborhood. IND also served as the SSND’s first motherhouse outside of Germany, anchoring its North American mission and allowing it to become a worldwide organization. Despite its closing in 2020 due to declining enrollment and funding, IND’s history, integrity, and contributions to women’s education highlight its significance. Currently part of the Old East Baltimore Historic District, this paper argues IND merits individual listing on the National Register of Historic Places for its architectural and historical importance. Additionally, this study outlines the research methodology employed, forming the foundation for a future National Register nomination.en-USWomen's HistoryWomen's EducationBaltimore, MarylandSchool Sisters of Notre Dame (SSND)National RegisterInstitute of Notre DameReport
