A lighting system on the outside and inside the structure emphasizes its shape, amplifies the effects and creates a suggestive atmosphere, especially in the evening. The Armungia nuraghe is a very rare case of nuragic architecture within a town: it rises amidst the rooves of the houses, a few metres from the old town hall, now home to the Sa domu de is Ainas museum, in the north-eastern edge of the town, the 'old part' of Armungia, to which it gives its name. The nuraghe is the most important archaeological feature of the territory, and overlooks the valley of the river Flumendosa: its strategic position may once have controlled the territory, and today it offers a splendid panorama that reaches as far as Gennargentu.
