The regular season opening of the Minnesota Vikings’ gleaming new $1.1 billion stadium was truly a grand one, filled with gray-haired legends, white-hot pyrotechnics and some purple rain for good measure.

And noise. Lots and lots of noise.

The Vikings opened U.S. Bank Stadium in earnest on Sunday night with a 17-14 victory over NFC North rival Green Bay, the culmination of a decade-long struggle to replace the drab and dingy Metrodome.

The fixed-roof beauty has already hosted a soccer game, a couple of concerts and two preseason football games. But this was its first truly big moment, with a showdown against the hated Packers in front of a primetime, national television audience serving as the perfect backdrop.

There were more than 20 stars from the team’s proud past in attendance, including the entire Purple People Eaters defensive line that led the Vikings to four Super Bowls in the 1960s and ‘70s. Hall of Famers Fran Tarkenton, Randall McDaniel and Cris Carter were there, too, and beloved former coach Bud Grant blew the gjallahorn to welcome the team to the field.

“For the first time ever, the best fans have the best stadium,” Carter said during an in-game interview. “This is the greatest platform we’ve ever had to perform.”

Pregame festivities included a huge party on the commons area in front of the stadium with live music for a crowd of thousands that piled into downtown Minneapolis hours before kickoff. As the game grew closer, the world’s largest pivoting glass doors opened on the west side of the stadium to allow nearly 67,000 fans to stream in, and the Vikings showed a video featuring Thor Bjornsson — The Mountain from “Game of Thrones” — who helped introduce a new cheer based on an Icelandic war chant.

Commissioner Roger Goodell attended to help celebrate a stadium that got more than $450 million in public money to ensure the team wasn’t lured away to Los Angeles. For the first time in recent memory in Minnesota, there weren’t thousands of cheeseheaded Packer fans from the east who breached the gates and hollered “Go Pack Go!” during the game.

The Vikings entered the field through six cauldrons that shot bright orange flames toward the roof, quickly answering questions about whether the fancy digs could match that old, claustrophobic pillowcase when it comes to ear-splitting noise.

The Packers were backed up near their own end zone on their first possession of the game, and the full-throated crowd created a din that rivaled anything that was heard at the Metrodome.

“It was awesome. The best environment I’ve ever played in,” Vikings tight end Kyle Rudolph said. “The crowd was amazing all night.”
