Monument Designation

National monuments make up some of America’s most celebrated icons, from California's Giant Sequoia National Monument to New York's Statue of Liberty.

With the stroke of a pen, the president of the United States can protect natural, historical and cultural wonders by designating them as national monuments. The president can do this by using the Antiquities Act, a law enacted by President Theodore Roosevelt.

Perhaps one of the greatest powers bestowed up the president of the United States is the ability to protect America’s treasures by using the Antiquities Act. Sixteen presidents — from Theodore Roosevelt to Barack Obama — have used the Antiquities Act to protect places big and small across the United States. 

National monument designation is a form of protection most like a National Conservation Area (NCA). National monuments are flexible designations that allow for a true conservation balance between development and the need to protect our most treasured places for our children and grandchildren.

How we designate national monuments

National monuments can either be established by Congress though legislation or by the president of the United States through the use of the Antiquities Act.

Sometimes when the wheels of Congress move too slowly, or there is extreme partisan gridlock, the use of the Antiquities Act is welcomed, especially when cries for protection on the ground have hit a brick wall in Congress.

Existing monuments

America celebrates more than 100 national monuments, many of which were designated through the use of the Antiquities Act.

Antiquities Act

Some of our most beloved places are here today thanks to the Antiquities Act. This popular law is used by the president to designate national monuments. Since its enactment in 1906, the majority of U.S. presidents have used it. The Antiquities Act has protected well known places like the Grand Canyon, which was a national monument before it gained national park status, and lesser known places, like the Pacific Remote Islands Marine National Monument.

    Today, the Interior Department's Bureau of Land Management announced a new methane waste rule to replace its own regulations that went into effect only about one year ago. The new rule eliminates important environmental and public health protections established under the 2016 rule and will result in increased natural gas waste and reduced taxpayer revenue.
