The New Mexico State Capitol, affectionately known as the “Roundhouse,” stands as a distinctive symbol of the state’s rich cultural heritage and architectural innovation. Located at 490 Old Santa Fe Trail in Santa Fe, it is the only circular state capitol building in the United States .
🏛️ Architectural Design & Symbolism

Completed in 1966, the Roundhouse was designed by architect Willard C. Kruger to embody the Zia sun symbol—a sacred emblem of the Zia Pueblo—when viewed from above. This design features a central circular structure with four protruding entrance wings, representing the four cardinal directions, seasons, times of day, and stages of life.
The building showcases a harmonious blend of New Mexico Territorial Revival, Pueblo Revival, and Greek Revival architectural styles. Its façade incorporates traditional adobe elements, while the interior boasts a 60-foot-high rotunda adorned with New Mexico travertine marble and a turquoise and brass mosaic of the state seal. The stained-glass skylight above mirrors a Native American basket weave, symbolizing the unity of sky and earth
🎨 Art & Cultural Exhibits
Beyond its governmental functions, the Capitol serves as a cultural hub. The Capitol Art Collection, established in 1991, features nearly 600 works by New Mexican artists, including paintings, sculptures, textiles, and mixed media pieces, displayed throughout the building.
On the fourth floor, the Governor’s Gallery, founded by First Lady Clara Apodaca in 1975, hosts rotating exhibitions that highlight the state’s artistic talent. Notably, the gallery’s inaugural exhibition featured works by Georgia O’Keeffe
🌿 Gardens & Grounds
The Capitol is set within 6.5 acres of landscaped gardens, known as the Clay Buchanan Memorial Gardens. These grounds feature over 100 varieties of native plants, including roses, sequoias, and Russian olive trees, as well as sculptures from the Capitol Art Collection
