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.
References:The Pilgrimage Church of Wies (Wieskirche) is an oval rococo church, designed in the late 1740s by Dominikus Zimmermann. It is located in the foothills of the Alps in the municipality of Steingaden.
The sanctuary of Wies is a pilgrimage church extraordinarily well-preserved in the beautiful setting of an Alpine valley, and is a perfect masterpiece of Rococo art and creative genius, as well as an exceptional testimony to a civilization that has disappeared.
The hamlet of Wies, in 1738, is said to have been the setting of a miracle in which tears were seen on a simple wooden figure of Christ mounted on a column that was no longer venerated by the Premonstratensian monks of the Abbey. A wooden chapel constructed in the fields housed the miraculous statue for some time. However, pilgrims from Germany, Austria, Bohemia, and even Italy became so numerous that the Abbot of the Premonstratensians of Steingaden decided to construct a splendid sanctuary.
