The ancient portal of Donna Annetta dates from the period between the late 1600s and early 1700s and served as the access to the Su Marchesu olive grove. Its stylistic features are among the oldest of all the portals that we find scattered in different parts of Sardinia: the architectural lines are related to a severe late-16th-century classicism interspersed with some proto-Baroque openings. It can be said that Donna Annetta’s portal is among the most important examples of rural architecture.
