For two weeks this September, all of the pieces of the U.S. Constitution will be on display together for the first time, the National Archives announced Tuesday.

The National Archives building is well-known as the permanent home of the U.S. Constitution. Anyone, D.C. resident or not, can stop by the Rotunda for free and admire the United States’ most vital legal document.

But those visitors have never been able to look at the entire Constitution — including all four pages of the original document through the most recent amendment — at one time.

The new, temporary display is part of the America 250 celebrations, marking the country’s bisesquicentennial all year long across the country.

Starting on Tuesday, Sept. 16, and open through Wednesday, Oct. 1, the display will showcase the following:

All four pages of the original Constitution.

The “fifth page” of the Constitution. This original document is only technically a part of the Constitution, and contains a set of instructions to the newly-formed states on how to implement the Constitution. It is signed by George Washington, who was then President of the Constitutional Convention, according to the Archives.

The Bill of Rights. The four-page original document contains the first 10 amendments to the Constitution, including freedom of speech, religion, the press and political activity.

The other 17 amendments to the Constitution ratified between 1789 and the present.

All four pages of the Constitution have been on display at the National Archives since 2003, when major renovations to the Rotunda were finished. And the “fifth page” has been put on display before, briefly in 2012, to celebrate Constitution Day.

But those five pages, the Bill of Rights, and the 17 other amendments have never been displayed side-by-side at the same time — until now.

The display will be “dramatic and highly visual,” according to the announcement from the Archives.

Visitors will be able to see the special display during the regular hours of the National Archives. The museum is open from 10 a.m. to 5:30 p.m. every day of the week.

The display also comes with extended weekend hours. The National Archives will be open until 7 p.m. on Saturday, Sept. 20, Sunday, Sept. 21, Saturday, Sept. 27 and Sunday, Sept. 28.

“As we approach the 250th anniversary of our nation’s founding, the National Archives is playing a major role in the coast-to-coast commemorations by providing the American people access to their history,” Jim Byron, senior advisor to the Acting Archivist of the United States Marco Rubio. “This extraordinary installation welcomes all Americans to celebrate the bedrock of our national life: our Constitution.”

Visitors should expect longer-than-normal wait times to get into the building and the Rotunda. You can reserve timed-entry tickets here.
