The medieval castle of Häme is located on the coast of lake Vanajavesi. It was originally located on an island.
The castle's age is disputed. Traditionally the construction of the castle has been connected to the legendary Second Swedish Crusade which would date the castle in the mid-13th century. However, there are no finds from the castle that can be firmly dated to a period earlier than 1320s. Also the contents of the crusade legend have been seriously contested. An earlier fortification from about 1300 only some 20 kilometres away in Hakoinen also makes a 14th century dating for Häme Castle more probable. Only one castle ("Tauestahus") is listed in Tavastia in a royal document from 1308. Also, the Russian Novgorod Chronicle only mentions one castle during their plundering of Tavastia in 1311, its description matching well with the castle in Hakoinen.
The construction of Häme castle probably started after the Novgorod invasion. The first castle was made of gray stone, and later bricks were used.
The castle lost military importance by the end of the 16th century. Its defensive systems were upgraded in the 18th century with bastions around the castle. The castle became a prison in the 19th century and served as such until 1953, when massive restoration work started. The castle has been a museum since 1988. Facilities can also be rented for private events.
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.
