Technical Preservation Assistance for Existing National Historic Landmarks
Designation of NHLs helps recognize, preserve, and protect important locations in American history. Designating a property as an NHL may provide it with additional protections from development, and may also make the property eligible for preservation grants and technical preservation assistance. Most NHLs are privately-owned and are governed by local preservation laws.
Preservation issues fall under the domain of regional NHL offices. Contact your regional office if you have questions about the preservation services they offer.
