Which Georgia O'Keeffe residence became a National Historic Landmark in 1998?

Georgia O'Keeffe's Abiquiu Home and Studio became a National Historic Landmark in 1998. The property in Abiquiu, New Mexico, was O'Keeffe's principal residence and workplace during the later part of her life.

O'Keeffe acquired the abandoned adobe house in 1945 and spent years renovating it. Its famous black door, courtyard, walls, and views of the surrounding landscape became important elements in her paintings and photographs.

The residence is separate from the Georgia O'Keeffe Museum in Santa Fe and from Ghost Ranch, although all three places are connected to her New Mexico story. The home and studio are preserved through the Georgia O'Keeffe Museum, which offers limited public tours.
