Before you contact the National NHL Program office, please note:

We do not administer individual National Historic Landmarks. Please contact a property directly to find out if it is open to visitors. Many NHLs are privately owned.

Because of the high volume of email we receive and limited staff resources we appreciate your patience.

For information on contacting the NHL National Office or the specific NHL regions please use our map.
