This map features sites and areas listed in the National Register of Historic Places, and it was created based on individual state sources/databases. The map also shows shipwrecks, a National Marine Sanctuary, National Parks, and other parks and reserves. The National Register of Historic Places (NRHP) was established by the National Historic Preservation Act of 1966. The NRHP database is a listing of sites (e.g., buildings, objects) and areas (e.g., large properties, districts) that have cultural or historical significance and are noteworthy for preservation. The dataset is a compilation of NRHP from state databases. Currently the map shows NRHP locations only in Maine, Massachusetts, New York, and Rhode Island.

Data Considerations

NRHP data for New Hampshire and Connecticut are not shown on the map because spatial datasets for those states are currently being developed. The NRHP sites in this dataset are from individual state databases/sources. Some NRHP sites may be missing from this dataset. However, states are working on updating their databases/datasets, and this regional dataset will be updated as states provide updates. Users must consult with appropriate State and/or Tribal Preservation Offices in the identification and evaluation of historic properties as stated under the National Preservation Act. This regional dataset compiled by Northeast Ocean Data serves as a baseline for identifying NRHP; users must confirm with appropriate State and/or Tribal Preservation Offices for official listings under the National Register of Historic Places. For more information and current listings of NRHP, please be directed to the National Park Service’s National Register of Historic Places site at https://www.nps.gov/nr/about.htm. The map also shows spatial data for the following features.

(1) Stellwagen Bank National Marine Sanctuary (SBNMS) is located north of Cape Cod and east of Boston. SBNMS is one of 14 marine sanctuaries nationwide and is the only marine sanctuary in the Northeast.

(2) Shipwrecks are shown on the map only at medium to high zoom levels.

(3) Parks and reserves from The Nature Conservancy’s 2012 Secured Lands dataset (publicly downloadable external version) include the following types of lands within 10 kilometers of the coast: nature reserves, preserves and sanctuaries; national wildlife refuges; wildlife managed areas; municipal forests, lands and parks; and state forests, lands and parks. The Secured Lands dataset shows public lands, private lands, and waters secured by a conservation situation that includes an explicit level of security from future conversion and current incompatible uses. The Nature Conservancy’s Secured Lands dataset is intended to include all permanently protected lands in the eastern 18 U.S. states and is compiled annually from over sixty sources. This map displays a subset of secured lands from the larger dataset provided by The Nature Conservancy’s Eastern Division. For the most part, it is a combination of public land information maintained by each state and private conservation land information compiled by the Nature Conservancy’s state field offices. The complete version of the Secured Lands dataset can be found here along with a detailed report and additional information. Please be advised that not all places included in The Nature Conservancy’s Secured Lands dataset and in the Northeast Ocean Data dataset are accessible to the public.


This map was last updated in February 2015. These data will continue to be updated as described in the 2016 Northeast Ocean Plan
