Documented Historic Landscapes

Since the Historic American Landscapes Survey (HALS) was established in 2000 to document our country's dynamic landscapes, much progress has been made in identifying and documenting historically significant designed and vernacular cultural landscapes. As documentation is submitted, the full list of HALS sites continues to grow. At the start of 2014, information on more than 450 sites was accessible on the Library of Congress’ website. There are more than 800 sites on the current list.

Below are a selection of documented HALS sites from across the United States that focus on a shared theme or feature, with links to the selected landscapes' documentation on the Library of Congress’ website. This page will be updated periodically to highlight different themes.

HALS Highlights

Since 2010, landscape architecture preservation enthusiasts from every state have been challenged to complete at least one HALS short format history to increase awareness of particular cultural landscapes. The theme for the 2022 HALS Challenge is Olmsted Landscapes. The deadline for submissions is July 31, 2022 and the winners of the HALS Challenge will be announced during the ASLA Conference on Landscape Architecture. In tandem with this year’s theme, below we highlight a few Olmsted landscapes already in the HABS/HAER/HALS Collection:

Mountain View Cemetery, HALS CA-39
Oakland, California

Rockefeller Carriage Roads, HAER ME-13
Acadia National Park, Mount Desert Island, Maine

Henry Hudson Parkway, HAER NY-334
New York, New York

Ladies’ Pavilion, Central Park, HAER NY-197
New York, New York

The complete list of HALS sites is viewable online, and we are working to get all locations on the map as well:
