Coddu Vecchiu is a Nuragic funerary monument located near Arzachena, dating from the Bronze Age. The site consists of a stele, stone megaliths and a gallery grave, and is one of the larger Nuragic Giants' graves on the island. The Nuraghe La Prisgiona is located nearby.
The site was excavated in 1966 by Editta Castaldi. Among the artifacts recovered were pans, bowls and plates with comb decoration, as well as vases with bent necks, and vase fragments of the early Nuragic Bonnanaro culture, suggesting the monument was constructed early in the Nuragic period c. 1800–1600 BC.
Coddu Vecchiu appears to have originally consisted of a cist, which was expanded during the middle Bronze Age c. 1800–1600 BC and covered with a gallery grave and the ornate stele portal stone and megaliths characteristic of Giants' graves. The stone forecourt consists of eleven granite stones arranged in a semicircle and measures about 12 meters across. It has been hypothesized that the semicircular arrangement of the stones may have been an attempt to harness the telluric current of the granite for rejuvenative purposes. The central stele stands about 4 meters high and contains the entrance into the tomb. The gallery grave extends behind the forecourt, measures about 10 meters long, and was probably once covered by a tumulus.
The upper portion of the stele was once taken by a local farmer and used as a plow, but it was soon recovered and restored to its place in the monument. Coddu Vecchiu is among the most well-preserved of Giants' graves, and continues to be a popular tourist attraction.References:
Roman Walls of Lugo are an exceptional architectural, archaeological and constructive legacy of Roman engineering, dating from the 3rd and 4th centuries AD. The Walls are built of internal and external stone facings of slate with some granite, with a core filling of a conglomerate of slate slabs and worked stone pieces from Roman buildings, interlocked with lime mortar.
Their total length of 2117 m in the shape of an oblong rectangle occupies an area of 1.68 ha. Their height varies between 8 and 10 m, with a width of 4.2 m, reaching 7 m in some specific points. The walls still contain 85 external towers, 10 gates (five of which are original and five that were opened in modern times), four staircases and two ramps providing access to the walkway along the top of the walls, one of which is internal and the other external. Each tower contained access stairs leading from the intervallum to the wall walk of town wall, of which a total of 21 have been discovered to date.
The defences of Lugo are the most complete and best preserved example of Roman military architecture in the Western Roman Empire.
Despite the renovation work carried out, the walls conserve their original layout and the construction features associated with their defensive purpose, with walls, battlements, towers, fortifications, both modern and original gates and stairways, and a moat.
Since they were built, the walls have defined the layout and growth of the city, which was declared a Historical-Artistic Ensemble in 1973, forming a part of it and becoming an emblematic structure that can be freely accessed to walk along. The local inhabitants and visitors alike have used them as an area for enjoyment and as a part of urban life for centuries.
The fortifications were added to UNESCO"s World Heritage List in late 2000 and are a popular tourist attraction.
