New London's Black Heritage Trail

New London’s Black Heritage Trail celebrates three centuries of Black strength, resilience, and accomplishment. Some of the trail’s fifteen sites explore nationally known people or incidents. Others honor people who have been nearly forgotten. Nearly all describe the determination with which New London’s Black community overcame obstacles through personal courage and by founding institutions to meet its social, political, economic and spiritual needs. Together, the sites tell a story about Black life in New London while tying into larger stories about enslavement, the Great Migration and the struggle for civil rights.

Sanborn Maps

Sanborn maps are old fire-insurance maps that consist of a uniform series of large-scale maps, dating from 1867 to the present and depicting the commercial, industrial, and residential sections of cities and towns across North America. Fire insurance maps are valuable to much historic research because they often provide evidence of change over time. Specific changes in an individual site such as when a building was expanded or torn down, can often be dated within a reasonably accurate time frame, depending on how many different map editions for that city are available. In print, Sanborn maps are available in various library and museum collections around the state. Online, too, many of them are available from various collections, including:
