Boston's historic maps offer a different way to explore a familiar block

A familiar corner can become less familiar when placed beside an earlier map. A vanished building, altered shoreline or different property boundary raises questions that an ordinary walk may never suggest. The Leventhal Map & Education Center's Atlascope gives Boston residents a way to begin that comparison from home.

The center has aligned more than 145 historical atlases from Massachusetts towns and cities with modern geography. Fire-insurance and real-estate maps can reveal buildings, owners and infrastructure in considerable detail. Choose one small area and compare available dates, keeping the map's purpose and date in mind rather than treating it as a complete description of everyone who lived there.

For an in-person visit, a current notice matters: the Leventhal Center gallery is closed September 14–October 30 for installation, with special preview days on October 23 and 24 from 10 a.m.–5 p.m. It is inside the Boston Public Library's Central Library at 700 Boylston Street. Confirm the notice before traveling.

Save the title and date of any map used in your research, and compare it with other records before drawing conclusions about a particular resident or building. Atlascope can identify a promising question without answering every part of it. One block studied carefully can turn a routine walk into an encounter with several versions of the same city.
