During the past few decades, the concept of historic preservation has grown beyond protecting a single building or urban district to include historic landscapes. ASLA partners with the National Park Service on an annual challenge to document historic landscapes in the United States and its territories to serve as tangible evidence of our nation’s heritage and development. Join us to hear the winners of the 2021 HALS Challenge, Historic Black Landscapes, be announced and to learn about the 2022 Challenge details.
