Map of Boston in the State of Massachusetts

Surveyed by the civil engineer John G. Hales, it is considered to be one of the most accurate maps of the 19th century expansion era, the first to show a comprehensive list of buildings. Different shadings were used to indicate the material from which a building was constructed. It shows property lines, data that, when coupled with those about buildings, provide invaluable information about Federal-period Boston. The map covers the Shawmut peninsula and includes an inset of Boston Neck.
