About this dataset
These points are directly sourced from the National Historic Landmarks, National Register, State Register, Local Historic Districts, Local Historic Places, Historic Resources inventories, CHC files, Connecticut Barns listings, Connecticut Arts & letters listings, Connecticut Making Places listings, Connecticut Freedom Trail listings, and various special surveys (Sculpture, Civil War Monuments, Municipal Parks, Town Greens, Historic Bridges). If a resource appears in multiple pdfs, it will appear as one entry.
The geolocation of these points is based on the addresses and pre-existing maps that appear in the associated pdfs of the resources. Some resources were unable to be geolocated; but will still appear in the attribute table of this layer.
The following is a list of the sources for each resource with their associated designation:
1). National Historic Landmark (NHL); with the designation “NHL”.
