The Castello Svevo or Swabian Castle (Castello normanno-svevo), also known as the Houhenstaufen Castle, is a castle in the Apulian city of Bari.
Probably built in 1132 by Norman King Roger II, it was destroyed in 1156 by king William I of Sicily and rebuilt and reinforced in 1233 by the Holy Roman emperor Fredrick II. During the Angevin domination, it went through several transformation, and after being acquired by Duke Ferdinand of Aragon, was donated to the Sforza family and passed to Bona Sforza, Queen of Poland. After Bona's death, it was returned under the King of Naples and transformed into a prison and barracks.
The castle is surrounded by a moat on all sides, except the northern section, which was bordering the sea and can be accessed from the bridge and the gate on the southern side. It is mainly composed of the Aragon walls and the main Hohenstaufen tower, and is currently used for exhibitions.
According to the tradition, in 1221 Emperor Frederick II met St. Francis of Assisi in this castle. According to tradition, the emperor had a courtesan sent to Francis's room and watched through a peephole to see what would happen. When Francis sent the woman away, Frederick was impressed with his principles; the two spent the rest of the night in conversation. This story is not confirmed beyond doubt, but it is considered believable.

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.
