Røros is a characteristic example of this type of technological and industrial development, as well as being an outstanding survivor of a traditional kind of human settlement built by traditional methods of construction. Also, it has vulnerable under the impact of economic change since the cessation of copper mining after 333 years of continuous activity. Lastly, Røros embodies a strong degree of rarity because of its location. It was built as an industrial community in the mountains (650 m above sea level) at a very northern latitude subject to extremely long winters and low temperatures (-50 °C).
Within the framework of Norway's inventory of cultural property, Røros ranks in importance with Bryggen and the stave church at Urnes. Røros is an extensive mining settlement dating from 1644, when the development of the copper works began. Its physical history has continued without interruption since the town was burned in 1679.
Thus the numerous surviving buildings represent the Norwegian tradition of construction that flourished in the 18th and 19th centuries. The buildings reflect the dual occupations of the inhabitants - mining and farming - the domestic groups being arranged as compact farmyards. These groups are disposed on a regular urban pattern adapted to the mountain terrain, reflecting the particular kind of industrial planning introduced by the Danish kings of Norway in the 16th and 17th centuries.
Røros is in a remarkably complete state of preservation. An engraving of the town as seen from the slag heaps in the 1860s is virtually the same as a photograph of the 1970s taken from the same viewpoint.
Preservation efforts date from the early years of the 20th century. The first legal protection of buildings in Røros was effected in 1923. Legal protection now extends to 80 buildings. In 1936 land was purchased for the development of an open-air museum, and the first old building was moved to the site in 1947. However, the museum impetus was overtaken by a movement, dating from 1938, that led to the preparation of plans for the preservation of the town and copper works.References:
Monte d"Accoddi is a Neolithic archaeological site in northern Sardinia, located in the territory of Sassari. The site consists of a massive raised stone platform thought to have been an altar. It was constructed by the Ozieri culture or earlier, with the oldest parts dated to around 4,000–3,650 BC.
The site was discovered in 1954 in a field owned by the Segni family. No chambers or entrances to the mound have been found, leading to the presumption it was an altar, a temple or a step pyramid. It may have also served an observational function, as its square plan is coordinated with the cardinal points of the compass.
The initial Ozieri structure was abandoned or destroyed around 3000 BC, with traces of fire found in the archeological evidence. Around 2800 BC the remains of the original structure were completely covered with a layered mixture of earth and stone, and large blocks of limestone were then applied to establish a second platform, truncated by a step pyramid (36 m × 29 m, about 10 m in height), accessible by means of a second ramp, 42 m long, built over the older one. This second temple resembles contemporary Mesopotamian ziggurats, and is attributed to the Abealzu-Filigosa culture.
Archeological excavations from the chalcolithic Abealzu-Filigosa layers indicate the Monte d"Accoddi was used for animal sacrifice, with the remains of sheep, cattle, and swine recovered in near equal proportions. It is among the earliest known sacrificial sites in Western Europe.
The site appears to have been abandoned again around 1800 BC, at the onset of the Nuragic age.
The monument was partially reconstructed during the 1980s. It is open to the public and accessible by the old route of SS131 highway, near the hamlet of Ottava. It is 14,9 km from Sassari and 45 km from Alghero. There is no public transportation to the site. The opening times vary throughout the year.
