For the lovers of archaeology, Arbus offers interesting nuragic finds. The nuraghe of Cugui is one of the most original in Sardinia: located on a hill in a panoramic point towards Fluminimaggiore, it is easily reachable from Canau place, known for its spring.

It has got three towers and only one of that is accessible from a not so high entrance. From it, it is possible to have a view of Arbus, Mount Linas and a part of Gonnosfanadiga.
