Grazia Deledda was the first woman to win the Literature's Nobel Prize in 1926. In Deledda's novels there is always a strong connection between people and places. The environment depicted is that of native Sardinia, mainly traditional Barbagia, with her characteristic natural landscapes and folk culture inside the mountains villages. The most popular novel of Grazia Deledda Reeds in the Wind ("Canne al vento") sets the scene mainly in the small village of Galtellì and presents the story of the Pintor sisters, a family of noble landowners in decline. Today Galtellì is the hearth of the Literary Park dedicated to Grazia Deledda with his well maintained historic centre characterised by low whitewashed houses.
