Mosaic Pieces

Welcome to the complete Maryland Mosaic. 

 

The Mosaic is not presented chronologically but presents a randomized selection of Mosaic Pieces to spark your interest in a particular event or person. If you would like to have a more ordered chronological overview, use the six fixed time period options on the right of the screen to get a more immediate picture of an historical period. You can also explore by county or by category. Our predefined categories, tags, counties and chronological brackets will help you see links between the Pieces.

 

The collection has over 140 firsts, including events, people, places, objects, documents or buildings that are unique to Maryland and to the nation. The Mosaic is part of Maryland’s contribution to the U.S. 250th anniversary in 2026. It covers the period from 1776 to the present. You will find at least one Piece for every county and Baltimore City, making this a statewide project.
