On the plateau of Talana stands the Bau e Tanca nuraghe, an articulated complex built entirely with imposing blocks of granite sourced from the outcropping rocks of the surrounding territory.
The monument's plan features a main tower connected to secondary structures that together define an intricate defensive perimeter. The use of granite, a hard stone that is particularly complex to shape, testifies to the high level achieved by local master builders in the technique of dry-stone construction.
Marked structural collapses and the dense accumulation of rubble obstructing the entrances prevent entry or a visit to the internal chambers. However, observing the monument from the outside makes it possible to appreciate the line of the masonry, precisely superimposed in horizontal courses that follow the slopes of the underlying rocky terrain.
In the areas adjacent to the main complex, numerous circular hut foundations emerge, belonging to a large settlement. During the Bronze Age, the site played a central role in organizing the area's agro-pastoral activities, enabling the management of mountain pastures and the surveillance of natural pathways descending toward the Rio Prama valley. Bau e Tanca thus preserves the concrete sign of human presence and community structuring in ancient Ogliastra.
