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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
