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".

Inside "Santa Sabina", a rotunda with two added side chapels, erected between the 10th and the 12th century.
