Silanus - Santa Sabina

This place just south of Silanus, named "Santa Sabina" (aka "Santa Sarbana"), seems to be "Sardinia in a nutshell". Here are a nuraghe, a "byzantine" church, a holy well, two "Tombs of the Giants" and foundations of a prehistoric village. And somehow all these structures seem "interconnected".

The nuraghe has a diameter of 12,60m and is, though the top part is obviously demolished, still about 8,60m high. It was erected during the Bronze Age (1600-100 bC). The stairs are inside the tower.
