Sometimes, change in an urban landscape is cause for celebration.

Like in Atlantic City this week, when the decimated town rid itself of the last trace of former casino owner Donald Trump’s reckless and overextended occupancy.

The implosion of the decaying Trump Plaza just after 9 a.m. on Ash Wednesday sent up clouds of dust, smoke and ash, as well as cheers and a chorus of car horns.

Folks paid $10 a car to park in the lot with the best view. Neighboring Caesars offered front-row rooms as part of an “implosion special.” There was even a bidding war for the right to push the button. (Though that ultimately felt too gauche, even for the seaside resort known for its flamboyance, and officials canned the idea.)

It was a belated Mardi Gras.

But in D.C., recent and equally momentous changes in the urban landscape got no fanfare.

And I’m not even talking about the dystopian decor of fencing, razor wire and troop presence around the Capitol, Trump’s legacy in the last town he occupied.

No, on the same day that Atlantic City partied over demolition, Washingtonians lamented the first steps in the dismantling of an architectural feature that had become an iconic site in the capital: the First Amendment to the U.S. Constitution, carved in Tennessee marble on the front facade of the now-closed Newseum.

“It’s too symbolic,” said a jogger who passed 555 Pennsylvania Avenue NW, as he looked up and noticed the huge panels missing from the 75-foot outer wall.

“Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances,” the panels had said since 2008.

Now several have been taken down, and the rest will be gone in March, as Johns Hopkins University prepares to move its Washington-based graduate programs into the building it bought from the Freedom Forum two years ago.

With “Cong,” “ake,” “pet” and other chunks missing, it’s a “Wheel of Fortune” puzzle with no Vanna White in sight.

The Poynter Institute called the removal “a heartbreaking symbol . . . [a] troubling reminder of how many Americans now view the media and the freedom of the press, wouldn’t you say?”

But Johns Hopkins says the grand display is “a museum artifact and was not part of the sale of the building.”

“As part of the extensive renovations to the facility, the tablet will be removed in March, and all artifacts owned by the Freedom Forum are being temporarily relocated to off-site storage,” university spokeswoman Jill Rosen said.

The Freedom Forum promised it won’t let it stay in storage for long. It’ll be on another building soon, a spokesman said.

When the Newseum opened in such a prominent location, halfway between the White House and the Capitol, after being tucked away across the Potomac in Rosslyn, Va., for 11 years, it was an important statement of our most fundamental freedoms.

Nevermind that the move happened just as the long-standing structure of the news business was crumbling.

It was an inspiration to truth, freedom and the mission of free speech even as newspapers folded and jobs were cut.

But after 10 million visitors over 11 years in D.C., the Newseum closed, too, racked by financial woes.

There’s no announcement on the future of the Newseum. But the future of that giant tablet is a hot topic.

“It’s super-important for us to display it,” said the forum’s spokesman, Jonathan Thompson.

But where?

“Across from the Trump hotel,” said a few people I surveyed this week.

“On the Mall,” another said.

“In every classroom in America,” someone else told me.

“Fake news!” said the lone skeptic, a reminder of the forces undermining journalism in the first place.

“It should be displayed at the entrance to the Capitol,” said Doug O’Connor, a saxophonist with the U.S. Army Band, whose idea was one of my favorites.

But why even display it at all?

Because it’s not only the news business that’s in real danger. The cultural shift in America — the people who want to silence protesters, who disrespect the integrity of professionals risking their lives to tell truth, the millions who believe propaganda over fact — don’t understand the First Amendment is in danger, too.

I watched self-proclaimed patriots on their way to storm the Capitol on Jan. 6, seemingly confounded by some of the amendment’s 45 words.

“Woo hoo!” yelled a platinum-blond woman, having read the amendment only up to the “religion” part. She took a few pictures of it.

“Do y’all know who said that? Whose quote is it?” she asked some of her friends. They had no idea.

This same group yelled “Fake News!” at a film crew asking to interview them that day.

The Freedom Forum said its monument to freedom of speech won’t be on display in D.C. And that’s okay. Because the amendment needs to be on display everywhere — government buildings, state capitols, town squares and in classrooms.

Because the same people who don’t respect it are the folks who don’t get Atlantic City.

They didn’t read the news stories about Trump’s legacy there. Journalists exercising their First Amendment rights reported on the bankruptcies, the small businesses that were unpaid and destroyed by the Trump Organization, and the way he took his money and ran, leaving behind economic carnage.

A sample New York Times headline in 2016: “How Donald Trump Bankrupted His Atlantic City Casinos, but Still Earned Millions.” Trump told them this was fake news.

And now, crowds of Atlantic City residents cheered as Trump’s abandoned casino was imploded by 3,000 sticks of dynamite, scrubbing his residue from their town. There was nothing fake about that.

The rest of the nation needs to do the same to the ignorance that Trump emboldened and encouraged, before those pieces of the First Amendment are removed, one panel at a time.
