Located on the north side of the Plaza, the Palace of the Governors is said to be the oldest public building in the United States. Built in 1610, the long, low abode structure with massive walls was the seat of government under Spanish, American Indian, Mexican and U.S. territorial rule until 1909, when it became the state history museum. Exhibits reflect the history of New Mexico and its varied cultures. The Palace Print Shop and Bindery features 19th-century printing presses and other equipment, all of which still operate. The
portal porch is a gathering place for American Indian artisans. Guided tours of the museum are available.
