These tombs are thought to be built by the Nuragic civilization, which were the same people who built the Nuraghes. Coddu Vecchiu As with other tombs, the facade is curved. This curve could be considered as part of a circle with a radius 13m in front of it. There are no centres for these circles, so their angle with the horizon is measured. In this tomb, for accuracy, it is the small back stone that aligns with the entrance. This is at 3° and could equate to 49 bc. The tomb is about 10m long and 3° at 10m in a triangle, which gives a side of 0.524m. At pi, it is 0.549m. ...
