Nuraghe Appiu
Description
Nuraghe Appiu archaeological park is surrounded by a suggestive and uncontaminated environment. It was probably born as anuraghe with only one tower, to which, later, other towers have been united, connected among them by corridors, outlining a quadrilobate figure.
In its simple form the nuraghe is a flat-topped conical tower built with stones of varying size laid without grout (dry walls). The masonry consists of courses of stone laid in more or less orderly fashion. In many cases the stones were laid as they were, but more often they were dressed to facilitate their laying. In the upper part of the towers, the part most exposed, the stones are usually dressed with care to ensure a perfect fit between the different elements and thus improve stability.
