The Hoberman Arch was the centerpiece of the Olympic Medals Plaza in downtown Salt Lake City during the 2002 Winter Olympics. Following the Olympics the arch was moved to the Salt Lake 2002 Olympic Cauldron Park where, along with the Olympic cauldron, it was one of the main highlights and an important part of Salt Lake's Olympic legacy. In August 2014 the arch was removed from the park and a new public display location is currently being planned.

The arch was designed by Chuck Hoberman to be used as a mechanical curtain for the Olympic Medal Plaza's stage. It is a semi-circular aluminum structure, which opened like the iris of a human eye. The arch design was inspired by Utah's natural stone arches, such as Delicate Arch. At the time of its construction the arch was the largest unfolding structure in the world.

It took Hoberman four months to design the arch (with support from Buro Happold). Specialized knuckle assemblies, which allowed the arch to expand and contract, were fabricated by Hudson Machine Works in Brewster, NY. These were paired with the arch's structural components and pieced together in its entirety by Scenic Technologies of New Windsor, New York, who spent an additional four months in constructing the arch in their warehouse in New York. It was then disassembled and then trucked to Utah, being reassembled in January 2002, and unveiled to the public and media by the Salt Lake Organizing Committee (SLOC), on January 25, 2002.

When installed at the medal plaza it would open to reveal a large 3D sculpture of the 2002 Olympic logo and a second Olympic cauldron, known as the Hero's Cauldron. The stage not only hosted award ceremonies, where the athletes received their medals, but was used as a concert venue during the Olympics; hosting many performing artists including Creed, Brooks and Dunn and the Dave Matthews Band.

Following the Olympics, plans to install the arch in some kind of park were formulated. Many of Salt Lake's citizens wanted the arch to be used in an amphitheater or some kind of concert venue, possibly at downtown's Gallivan Center or Pioneer Park. But because the arch was a symbol of the 2002 games, the United States Olympic Committee put restrictions on possible future locations for the arch (to protect Olympic sponsors from other businesses who do not have Olympic sponsor contracts). Because of these restrictions, and a lack of consensus among Salt Lake's leaders on where it would go, SLOC announced plans, on December 5, 2002, to install the arch at the Salt Lake 2002 Olympic Cauldron Park.

On July 30, 2003, the arch was lifted onto its new base at the park using 3 cranes. The arch was located just outside the park's southern fence and was partly open which allowed visitors to walk through it, while at night the arch was lit with multicolored lights. The arch was removed from the park in August 2014. On December 6, 2014, pieces of the arch were stolen from an impound lot where it had been stored.

The arch is 36 feet (11 m) tall, 72 feet (22 m) feet wide, and weighs 31,000 pounds (14,000 kg) It is made up of 4,000 individual pieces put together as 96 connected panels and are connected with 13,000 steel rivets. The 96 panels vary in size, but the largest are 9 feet (2.7 m) tall and 5 feet (1.5 m) wide. The panels are also translucent which allowed light from behind to be seen and echoed the 2002 Olympic theme Light the Fire Within. Two 30-horsepower motors controlled eight separate cables which pulled the mechanical curtain open in about 20 seconds. When the arch was fully opened it had folded up into a 6 feet (1.8 m) ring, which framed the stage.

Because of the potential of strong storms during the games, the arch was built to operate in extreme weather, including up to 70-mile (110 km) -per-hour winds.
