In 1746 Brynolf Brunou was granted to establish an ironworks to the Juankoski rapids. Juankoski was in the periphery of Sweden borderlands with no roads or cities. Water routes were the only way to transport goods. Juankoski became the only ironworks in Finland which used only the bog iron to manufacture different kind of tools.
The heyday of Juankoski was between 1851 and 1900 when it was owned by Anastasia Ponomareva, a Russian aristocrat. In her time the manufacturing process became more efficient and better transport routes were built to ship products. The village around grown to 1,000 inhabitants. The iron manufacturing ended in 1915 when Juankoski was acquired by Kemi Oy and moved to carton mill.
The ironworks area is a well-preserved sample of the industrialism history in Finland. The oldest building is the empire-style mansion built in 1826. The blast furnace is today a museum exhibiting the life of the ironworks society. There are also a bakery, cafe and handicraft shops. Guided walking tours are available in summer season.
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.
