Krevo Castle is one of the oldest Belarus castles and dates from the early 14th century. It is an important place in Belarus because it was the first all-stone castle to be built in the region. The stone walls were 2.5m thick and 13m high. The castle had two towers which guarded the rest of the fortress. Grand Duke Keistut was murdered in the castle in 1381, and in 1385 the famousKrevo Union (between Poland and the Grand Duchy of Lithuania) was signed here.
During the 16th century the Tatars and the Russians tried to capture the castle but it remained intact. By the early 19th century the castle was abandoned and the buildings were mostly destroyed during World War I. Today only the ruins of the castle remain. The perimeter walls can still be seen, but only a few fragments of the towers are still intact. There is a magnificent view of the ruins from the top of nearby Yuryeva Mountain.
Many legends surround the Krevo Castle ruins, including tales of an underground tunnel from the castle to Vilnius, and a beautiful princess who was bricked up alive in the castle walls. There is a pagan temple on Yuryeva Mountain and 1 of 4 amulet boulders, which used to lie at the entrance of Krevo to protect the town against trouble and disease, still remains.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.
