When you approach the University of Wyoming’s Centennial Complex, you’re met with an imposing sight: a massive cone rising from the earth, its dark metal skin catching the Wyoming light. It’s unlike any other building on campus—or frankly, anywhere else. This is exactly what architect Antoine Predock intended.
A Building for Wyoming’s Second Century
The Centennial Complex, which opened in 1993, houses both the American Heritage Center and the University Art Museum. The building’s name commemorates the University of Wyoming’s 100th anniversary in 1986, when planning for this ambitious project began. At 137,000 square feet, it represented the most ambitious fundraising campaign in the university’s history to that point, with goals to raise $19 million for construction plus an additional $6 million for endowments.
The campaign marked a significant shift in how UW approached building projects. As Dr. Terry Roark, who served as university president during the complex’s development, recalled in a 2021 oral history interview, the Wyoming Legislature had traditionally been the major source of university funding. This new initiative “began a trend of substantial private contributions, bolstered by matching state funds, that kicked off a new era of growth around campus.”
Predock’s Vision: An Archival Mountain
New Mexico-based architect Antoine Predock (1936-2024) won the commission for what would become one of his most distinctive works. Predock, who has described his approach as rooted in landscape and cultural memory, saw the building as emerging from Wyoming’s dramatic geography.

“Throughout Wyoming there is a sense of landscape in formation,” Predock explained.
The appearance of this ‘archival’ mountain can be thought of as parallel to the slow but certain geologic upheaval.” The cone—which contains the American Heritage Center’s collections and offices—was deliberately aligned with Medicine Bow Peak to the west and Pilot’s Knob to the east, anchoring the building into both campus and landscape.
At the core of this “mountain” is a hearth with timber framing that guides a central flue up through the building to a skylight. This space, known as the Mary Storer Loggia, serves as the building’s spiritual center. Floor levels wind around this hearth in a spiral, rotating as they ascend toward the sky-lit upper reaches.

The Art Museum, by contrast, resembles “a village at the foot of a mountain,” with galleries arranged in a more horizontal fashion adjacent to the cone. Predock described the overall design as recalling “the gathering of Native Americans, French trappers, and early European settlers. Now it is a place of intellectual and social rendezvous.”
The Road to Completion
The path to opening day was not without challenges. When Dr. Roark arrived as president, the American Heritage Center was housed in Coe Library, while the Art Museum occupied cramped quarters in the basement of the Fine Arts Building. Both institutions desperately needed space and proper facilities.

The campaign to fund the complex proceeded even as the AHC faced internal turmoil with the controversial dismissal of a longtime director. As Roark recalled, “My main concern was there were good people out there who supported the American Heritage Center and what it wanted to do, what its mission was, but they got tied up in [this director]. Despite this challenge, major donors came forward. The AHC portion of the building was named for Eleanor Chatterton Kennedy, daughter of former Wyoming Governor Fenimore Chatterton, and for Joe and Arlene Watt, cattle ranchers and descendants of Wyoming pioneers.
Roark remembered Kennedy’s substantial gift of Colorado land, though development restrictions limited its ultimate value. He also recalled the memorable moment when Joe and Eleanor Watt gave a million-dollar contribution: “It’s the only time I have ever held in my hand a check for a million dollars, but Joe and Eleanor Watt wrote, just like you’d write a check to the grocery store. Nothing fancy about it. Handwritten and just an ordinary check and for a million dollars.”
At one critical juncture, the UW Foundation considered withdrawing from the project. Roark recalled telling them firmly: “No, you can’t do that, or we don’t have the Foundation.”
Opening Day
Ground was broken on October 6, 1990, with Governor Mike Sullivan and President Roark each holding a side of an old-fashioned dirt scoop hitched to a horse. The Wyoming wind blew Sullivan’s signature hat away during the ceremony—an appropriately Western moment.
Three years later, on September 10, 1993, Sullivan and Roark cut the ribbon to officially open the facility. The dedication ceremony included traditional elements: an elder from either the Arapaho or Shoshone tribe conducted a peace pipe ceremony with the governor, president, and museum and AHC directors seated on a cloth on the ground. Roark, a lifelong non-smoker, took his ceremonial puff and spent the rest of the day trying unsuccessfully to rinse the taste from his mouth.

A Building That Teaches
Today, the Centennial Complex stands as one of the most distinctive buildings in Wyoming and a landmark of 1990s American architecture. The AHC has become one of the largest and most heavily used non-governmental archives in the United States, drawing approximately 5,000 researchers annually from all 50 states and numerous countries. Its collections have grown to 75,000 cubic feet—the equivalent of 18 miles of material—covering Wyoming and Western history, the petroleum and mining industries, politics, conservation, journalism, transportation, and 20th-century entertainment.
The Toppan Rare Books Library, located within the complex, houses more than 60,000 rare books and manuscripts, serving as an active teaching site unlike most rare book collections. The building’s galleries, classrooms, and reading rooms regularly host UW classes learning to conduct archival research.

The “archival mountain” Predock designed continues to serve its purpose: gathering people together around the stories and materials that illuminate our past and inform our future, all while standing as a striking architectural statement anchored firmly in the Wyoming landscape.
