Which Presidents Have Created the Most National Monuments?

About one-quarter of current sites within the National Park System originated through the Antiquities Act — a 1906 law that allows the president of the United States to proclaim lands or waters under federal jurisdiction as national monuments to maintain the integrity of critical natural and cultural resources.

President Theodore Roosevelt was the first president to use the Antiquities Act. He created Devils Tower National Monument in Wyoming soon after he signed the law. A total of 17 presidents — representing both political parties — have used the Antiquities Act to create nearly 160 national monuments, some of which are managed by other federal agencies.

President Joe Biden designated Camp Hale-Continental Divide National Monument in Colorado in October using the Antiquities Act. He has pledged to designate Avi Kwa Ame National Monument in Nevada, while vowing to protect more treasured lands.

NPCA applauds his work. The Antiquities Act “is a way for presidents to leave their mark on places beloved by the public, to inspire communities to amplify their stories and to conserve lands for future generations,” explained Kristen Brengel, NPCA’s vice president of government affairs.

“We have a choice to destroy or to preserve. Presidents have been inspired to designate monuments to reflect our collective heritage and honor all who have lived in these spaces, and we encourage President Biden to continue preserving and diversifying our park system through the Antiquities Act,” she said.

Looking back, who in the past 100-plus years has used the Antiquities Act the greatest number of times? The top 10 presidents for the number of monuments they created using the Antiquities Act are:
