Santa Fe's intriguing mix of Native American, Southwestern and Spanish influences is reflected in the city's vibrant arts community, as well as its architecture and ambiance. Among several prominent art museums, the Georgia O'Keeffe and the Museum of International Folk Art are perhaps the best known. Other popular museums include the 19th-century-themed Rancho de las Golondrinas. Visitors to the older sites of Santa Fe won't want to miss the Palace of the Governors, the oldest continually inhabited building in America, or the city's plaza, another major landmark.
