Start with the main building. Palmavera is what archaeologists call a complex nuraghe: a central body with two towers, built from blocks of limestone and sandstone, wrapped by an antewall. Sardinia has thousands of nuraghi, but few combine so much in one place. The excavator who first dug here, Antonio Taramelli, was struck by how the building worked. He noted the careful structure of the buttress, the clever arrangement of stairways, entrance corridor, courtyard and storage niches. To him these revealed a building that was inhabited and frequented, one where people could move about safely and store a good quantity of goods. At the same time, the height and strength of the walls, the difficult connection with the outside, the arrow slits in the tower and the many complicated closing systems at the entrance showed that it was also built to be defended. So think of it as home and stronghold at once. When you stand beside those walls, try to picture the interior as a place of daily routine, with stairs to climb, goods tucked away and a heavy entrance that could be shut against trouble.
