Santa Fe was Georgia O'Keeffe's principal home during her final years.
O'Keeffe moved from Abiquiú to Santa Fe in 1949, after the death of her husband, Alfred Stieglitz. She continued to work in New Mexico and maintained a strong connection with the region's landscapes, buildings, and objects. Santa Fe became an important base for her later life, even though Abiquiú remained closely associated with her studio and the settings depicted in many paintings.
O'Keeffe died in Santa Fe on March 6, 1986, at the age of 98. Her ashes were scattered over the Cerro Pedernal, a mountain she had repeatedly painted and described as her private mountain.
Taos and Abiquiú are both important New Mexico locations in O'Keeffe's story, which can make the answer seem interchangeable. She visited Taos early in her New Mexico years and lived at Abiquiú for decades, but Santa Fe was her final principal home and place of death.
