At 1,834 meters, Punta La Marmora is the highest peak in the whole of Sardinia. It is located in the Gennargentu massif, between the municipalities of Arzana and Desulo, and is named after the general and scientist Alberto Ferrero della Marmora, who described the Sardinian island in two scientific-literary works.

It may not be obvious that Sardinia's highest mountain is crowned by an imposing summit cross, but it seems completely natural to the mountain hiker. A base made of natural stone from the surrounding area forms the lower level of this small sacred monument. A round column bears the Latin inscription "Ave Crux spes unica" (loosely translated "Hail [holy] cross, [you] our only hope") and continues further up - almost seamlessly - into the longitudinal beam of the cross. Like many other summit crosses, it is comparatively simple in its design and has no corpus, but is certainly dignified.
