At first glance, it looks like a single-tower nuraghe, while in reality its complex structure is barely visible and, in addition, it was already ‘renovated’ in the protohistoric age, using a different material. The Corvos nuraghe stands alone in the countryside south-west of Florinas, about ten kilometres from the town. The central tower, eight metres high and with a diameter of 13 and a half metres, is still in good condition, which you will see in its dual colouring. At the base, it has large blocks of roughly-hewn limestone, while well-crafted dark trachyte ashlars were used during the renovation. It is not clear whether the work was the result of a collapse of the upper level or the choice to build it from scratch later on. The first hypothesis seems to be supported by the fact that there are also traces of repairs in the limestone masonry on the north-east side and therefore the possible probably occurred on this side.
