Villagrande Strisaili, Tomb of the Giants by Pradu Su Chiai

The monument is located in Santa Barbara, on the east bank of Lake Flumendosa, in an area on the border between Ogliastra and Barbagia, in central-eastern Sardinia.
The Tomb of Giants, also known as Campu de Pira Onni, is an isodomo-type burial with a “toothed frieze”. It is built with granite blocks.
The grave body (length 10.00 m; width 4.50 m) is made of well-worked blocks arranged in regular rows when retreating. At the apse there is an ash shaped like a circle. The internal funeral corridor, rectangular in plan (length 7.00 m; width 0.70/0.90 m), is built with horizontal rows of perfectly worked ashlars, larger than the basic ones. Starting from the third row, the blocks have a blurred visible surface. The bottom side is closed by a single headboard, while the floor preserves the pavement. The walls of the chamber are reinforced on the outside by a row of large ashlars that runs along the entire perimeter of the tomb and that also continues on the back of the wings of the exedra. Today, there is a single flat slab (length 2.00 m; width 0.70 m) inverted during work on the arrangement of a trellis. The entrance to the burial chamber is delimited by two well-worked rectangular ashlars, with a beveled angle, on which rests an lintel that has two vertical notches for better fixing the manhole. On the lintel lay a trapezoidal “toothed” frame with a slightly arched upper surface (h. m 0.90; width m 1.30/0.80; thickness m 0.36/0.18). The hemicycle of the exedra (rope m 12.80; thickness m 4.00/2.80) is made of orthostatic plates that rest on a base of machined blocks. The support base protrudes from the alignment of the orthostats, forming a double bench-seat. The area in front of the exedra is bounded by a stone fence. Within this sacred space, a second rectangular toothed frame (length m 0.75; width m 0.46) and a rectangular manhole (h. m 0.75; width m 0.72) were found with two drafts of maneuvers.
The tomb dates back to the recent Bronze-Final Bronze (1300-900 BC)

History of excavations
The burial was excavated by Maria Ausilia Fadda in the 80s of the twentieth century.

How to get there
Starting from Tortolì, take the direction of Villagrande Strisaili, taking first the SS 198, then the SP 27 to the center of the town. From there you exit and take the road that leads to the Alto del Flumendosa Lake. After about 1.5 km, at a right bend, leave the paved road and turn left into a small downhill road with a natural background. After passing two gates and a stream, after about 350 m, you arrive at the tomb enclosed in a fence of tree trunks, about 50 m away on the right of the road.
