Château de Sedan is a castle situated in Sedan, France, near the river Meuse. Covering an area of 35,000 square metres in its seven floors.
Around 1424, Eberhard II von der Mark built a manor with two towers around a church over a period of six years. When Eberhard died in 1440, his son Jean de la Marck began reinforcing the fortress, but it was Robert II de la Marck, the grandson of Jean, who finished the most important work. In 1530, the fortifications of the manor were modernised by the construction of a circular boulevard and terraces with cannons, thickening the 4.5-metre curtain wall by an additional 26 metres (85 ft). The bastions were added during the course of the next century, but some of them were eventually dynamited at the end of the 19th century. In 1699, the principality having been absorbed into France in 1642 (during the Thirty Years' War), and the castle having been transformed into a garrison, Vauban built the door of the Princes that was adapted to the progress of artillery. In 1822, the Church of Saint-Martin was demolished and replaced with a store for cannonballs.
On September 1, 1870 during the Franco-Prussian War, the Army of Chalons was defeated at the Battle of Sedan. Napoleon III surrendered the following day in the small neighboring city of Donchery.
The castle was used as a military hospital by the German army in World War I. Sedan was also the site of a French loss to the Germans in World War II in the Battle of Sedan (1940).
The castle was given by the French Army to the city of Sedan in 1962. Today the castle contains a hotel and a museum showing the lives of inhabitants throughout its history and the Franco-Prussian War.
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.
