New Mexico State Capitol

The New Mexico State Capitol, located in Santa Fe, New Mexico, is the house of government of the U.S. state of New Mexico. It is the only round state capitol in the United States, and is known informally as "the Roundhouse".

The building was designed to resemble the Zia Sun Symbol when viewed from above, with four entrance wings that protrude from the main cylindrical volume. Architecturally, the Capitol is a blend of New Mexico Territorial Revival style and neoclassical influences. Above each entrance is a stone carving of the State Seal of New Mexico. The building has four levels, one of which is below ground.

Dedicated on December 8, 1966, the building was designed by W.C. Kruger and constructed by Robert E. McKee. Its extensive marble-work was installed by the New Mexico Marble and Tile Company. The capitol contains 232,346 square feet (22,000 m²) and was built for the cost of $4,676,860, or $20 per square foot ($215/m²).

The capitol houses the New Mexico State Legislature. The first floor (below ground) contains the semicircular House and Senate chambers, which are not accessible to the public. The second story, which is the ground floor, includes galleries where visitors can view the House and Senate chambers. The House gallery seats 281 people and is located on the south side of the building. The Senate gallery, which seats 206 people, is on the north side of the building. The two upper floors are mainly offices, with legislative committee offices on the third floor and the offices of the Governor, Lieutenant Governor, and Legislative Council Service on the fourth floor.

The Rotunda in the center of the building is 49 feet (15 m) in diameter and 60 feet (18 m) high, spanning the second, third, and fourth floors. The Rotunda is finished with Travertine marble native to New Mexico and inlaid with a turquoise and brass mosaic of the Great Seal of New Mexico. The ceiling skylight is designed to resemble an Indian basket weave, with blue and pale pink stained glass representing the sky and the earth, respectively. The flags of New Mexico’s 33 counties are on permanent display on the fourth floor balcony.
