The New Mexico State Capitol, commonly called the Roundhouse for its circular design, operates under dedicated ZIP code 87503 in Santa Fe. Dedicated in 1966, the 232,000-square-foot building is the only round state capitol in the United States. When viewed from above, its shape resembles the Zia sun symbol featured on New Mexico's state flag. The Capitol houses both chambers of the state legislature along with offices for the Governor, Lieutenant Governor, and Secretary of State.
Two delivery codes route mail to the State Capitol building at the corner of Old Santa Fe Trail and Paseo de Peralta. The travertine-finished rotunda rises 60 feet at the building's center, featuring a turquoise and brass mosaic of the Great Seal of New Mexico. This government designation has served legislative correspondence for over two decades. No Census population data is available, consistent with its function as a government office building rather than a residential address. Santa Fe is the valid mailing city.
