The Essex Company
The Essex Company, was the engineering firm that planned and built the city of Lawrence, Massachusetts. They vacated the building in the 1970s, donating to The Lawrence History Center as their home. They are the trustees of the City’s past, maintaining archives of everything from the original plans of the city to land deeds to arrest records to (my favorite artifacts) glass plate negatives of the city’s earliest days.
Sweet! Love those rails as leading lines Bob
