About Us

The Baltimore-Rotterdam Sister City Committee (BRSCC) is a volunteer-run committee based in Baltimore that conducts the sister city affairs. The committee is part of the Baltimore Sister Cities association, a 501(c)(3) non-profit that manages the sister city relationships that were established by Baltimore Mayor’s Office.


Baltimore-Rotterdam Sister City Committee (BRSCC) promotes economic, cultural, educational, health/environmental and other cooperation and exchanges between Baltimore, Maryland, USA and Rotterdam, the Netherlands, and supports Baltimore regionís other activities and programs related to the Netherlands and the local Dutch community.

Our Activities



About Sister Cities

Sister-city relationships are overseen by the international non-profit organization Sister Cities International. These programs foster cross-cultural understanding and cooperation through the activities of ordinary citizens within the context of long-term, officially-sanctioned, municipal relations.

Baltimore has relationships with several sister cities. Volunteer-run sister city committees manage 5 of the sister city relationships; these committees are affiliated with the Baltimore Mayor’s Office. The committees are local residents who share an interest in cultural exchanges and who volunteer their time to bring the benefits of international relations to Baltimore.
