Libštejn castle is located above the Berounka south of Liblín in the Rokycany district. The castle was built by the royal construction manager Ulrich Tista von Liebstein as a private residence and was first mentioned in writing in 1361. At the end of the 14th century the castle came into the possession of the lords of Kolowrat. In the Hussite Wars belonged Libštejn Bedřich von Kolowrat, who, together with his brother Hanuš, was an important opponent of the Hussites.
In 1425 the castle was besieged by the Hussites and shot at from the surrounding hills. After seven weeks of siege, the two brothers signed an agreement with the Hussites and switched to their side. In 1590 the castle was mentioned as desolate. The main building of the castle were two adjoining palas buildings, which formed a small elongated courtyard in the middle. On the short sides, the courtyard was accessed by a square residential tower. The hilltop castle was built between three other higher peaks. This militarily unfavorable choice of location is due to the calm and stable times of Charles IV.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.
