The nuraghe of La Prisciona is currently (Sept 2007) closed to the public for repairs and excavation, likely to continue until at least May 2008.
The new excavations are revealing a whole series of buildings/rooms surrounding the nuraghe which has a triangular base and 3 towers, and a deep well in its courtyard.
The information office at Coddu Vecchju about 900 metres away shows some images of the excavations.
