Ammon News - It's been dubbed the "Arc de Trump." But now President Donald Trump's latest building project has an official name the "United States Triumphal Arch."

White House Press Secretary Karoline Leavitt revealed the formal title on Wednesday, saying the giant structure was being built to mark the 250th anniversary of US independence, AFP reported.

"In honor of this historic occasion, President Trump and the Department of Interior will submit plans for the United States Triumphal Arch," Leavitt told reporters.

Showing off a picture that she initially held upside down, Leavitt said the "monumental" arch would stand 250 feet (76.2 meters) tall "in honor of 250 years."

Its colossal height, including a huge golden Lady Liberty statue on top, means it will dwarf perhaps its most famous predecessor, the Arc de Triomphe in Paris, which stands at 164 feet.

In fact it is set to be the largest structure of its kind in the world, pipping Mexico City's Monument to the Revolution and knocking Pyongyang's Arch of Triumph to third place.

Plans for the arch were first revealed in October when AFP journalists spotted a model on Trump's desk in the Oval Office, after which it was quickly dubbed the "Arc de Trump" by US media.

Trump revealed the first full renderings for the structure last Friday.

The arch is one of several architectural projects including the construction of a gigantic White House ballroom and renovations to the Kennedy Center for the Performing Arts that Trump has undertaken to leave a mark on Washington in his second term.

Critics say the gold-accented arch, which will tower over the 99-foot-tall Lincoln Memorial, is a monument to the 79-year-old Trump's vanity.

The arch will partly be funded by US taxpayers, getting $2 million in special funds from the US National Endowment for the Humanities, with up to $13 million in funds to match any donations, ABC News reported.

But Leavitt said it was aimed at celebrating US national pride.

"Long after everyone in this room is gone, our children and grandchildren will remain inspired by this national monument," she told reporters.
