The Maryland Mosaic was created in celebration of the 250th anniversary of the United States. The Mosaic is a collection of people, places, events, buildings, documents, and objects. The collection provides a unique picture of this small border state through the lens of its geography, political influence, participation in military conflict, and long history of collaboration between Black and White citizens. It has a statewide reach as at least one Mosaic Piece represents every county and Baltimore City.
