Palace of the Governors

Now a Southwestern history museum, the Palace was constructed as a government building by the Spanish in 1610.
It remains the nation's oldest public building still in continuous use. The building faces Santa Fe's downtown Plaza, and American Indian artists sell their wares under its historic portal. Originally constructed in the early 17th century as Spain's seat of government for what is today the American Southwest, the Palace of the Governors chronicles the history of Santa Fe, as well as New Mexico and the region.
This adobe structure, now the state's history museum, was designated a Registered National Historic Landmark in 1960 and an American Treasure in 1999.
