The site of Filitosa is approached down a track through an ancient olive grove. The first monument to be seen is a rock overhang and surrounding wall. Then the visitor comes upon the central monument. Various hut platforms are all around, and the track leads a further 50m to the Western Monument or torri. From there, one can enjoy a view down the hill to a stone alignment of five megaliths, set around the base of a 2000-year-old olive tree. Behind the olive tree is the quarry from which the megaliths were extracted.
