WASHINGTON (AP) — It looks from afar more UFO than UFC.

Maybe it’s the kind of contraption that has carried space aliens to the White House to force a meeting with America’s leader.

But come closer and you’ll see the contours of the eight-sided cage, 30 feet in diameter and shaped, with careful precision, like the MMA league’s signature Octagon.

That is, a STOP! sign flipped on its edge, with wire-mesh sides and padded corners fitted with different sponsors’ logos: Morgan & Morgan, Bud Light, Dodge Ram, Corona Extra and Polymarket, which identifies itself as the world’s largest prediction market.

Overhead looms The Claw, a four-sided mass that arcs more than 90 feet into the air and features lights, speakers, thick snakes of wiring and four large screens so fans not seated right next to the Octagon can follow the cage fighting below.

Think more of the four-sided, metal grabby thing that tries to grasp stuffed animals at a video arcade rather than what house cats have — hence the extraterrestrial vibes.

And surrounding all that are risers filled with gray folding chairs forming a temporary arena expected to seat 4,000-plus people for the seven UFC fights being staged on Sunday to celebrate the 80th birthday of President Donald Trump and the 250th anniversary of the Declaration of Independence’s signing.

For non-UFC fans, all of this might be disorienting under any circumstances. But the temporary arena is covering nearly the entirety of the White House’s South Lawn, where Marine One usually lands to ferry the president to out-of-town trips and gobs of kids scramble in the grass during the Easter Egg Roll every spring.

More than $60 million and tens of thousands of hours of labor have been poured into building the arena, according to a court filing from the National Park Service, which oversees the South Lawn and is contesting a lawsuit meant to block the event.

The White House says the UFC is covering the costs, though the filing states that seven agencies — including the Department of Homeland Security and the Federal Aviation Administration — have “allocated significant resources and manpower.”

Fighters, their entourages and assorted support staffers are expected to take over the driveway and part of the West Wing when they’re not fighting. But they’ll enter the arena via curtained-off walkways with access to the Octagon.

They, as well as ordinary attendees of Sunday’s spectacle, will have picturesque views of the White House’s Executive Residence and its storied Truman Balcony on one side and the Washington Monument towering in the distance on the other. All of it will be accentuated by swirling spotlights, and perhaps even sweat and blood pouring off the fighters pummeling each other.

A packed pre-event schedule includes a press conference at the Lincoln Memorial with UFC chief Dana White and the fighters on Friday night.
