Marinmuseum (Naval Museum) is Sweden's national naval museum, dedicated to the Swedish naval defense and preservation of the country's naval history. Marinmuseum is one of Sweden's oldest museums, established in 1752 when King Adolf Frederick began the collection and documentation of naval objects in what was called the Model Room (Modellkammaren). He also ordered the preservation of ship models and ship building machinery.
The rectangular building design includes a pier which extends into the water. Around the pier are several museum ships. A specially designed underwater tunnel with windows provides a way to view the wreckage of several seventeenth century ships.
Figureheads from Swedish ships are on display, including many that were made by sculptor Törnström, royal sculptor to the navy, who worked at the Karlskrona shipyard during the 1700s. These include the figurehead of the ship the Dristigheten. The Marinmuseums Archives include 4,000 drawings and maps, mostly relating to the Sweden's Naval history; there are also pictures, paintings, and models. Subjects include submarines, shipbuilding strategies, battle tactics, and life on board ships of the Baltic Sea.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.
