During the past twenty years, the concept of historic preservation has grown
beyond protecting a single building or urban district to include the historic
landscape that provides the setting and context for a property as well as
much larger landscapes that have regional and national significance.
The Historic American Landscapes Survey (HALS) was established by the
National Park Service in 2000 to document landscapes that serve as tangible
evidence of our nation’s heritage and development. In addition to chronicling
significant and increasingly at-risk landscapes for future generations, HALS
provides a wide range of practical uses today. HALS is a companion program to
the Historic American Building Survey (HABS) and the Historic American
Engineering Record (HAER), which have chronicled the country’s most
significant structures over many decades.
