The Boston Public Library (BPL)’s Leventhal Map & Education Center is holding a free, virtual event where residents can learn about the history of the Jamaica Plain neighborhood via the BPL’s Atlasope program. Called Jamaica Plain by the Map, the event will provide a brief geographical history of the neighborhood from the late 19th and early 20th centuries and show how it has changed over the years, as well as highlight the Leventhal Map & Education Center’s Atlascope tool and how the public can use it.
