The Kraków Barbican is a fortified outpost once connected to the city walls. It is a historic gateway leading into the Old Town of Kraków. The barbican is one of the few remaining relics of the complex network of fortifications and defensive barriers that once encircled the royal city. It currently serves as a tourist attraction and venue for a variety of exhibitions.
The Gothic-style barbican, built around 1498, is one of only three such fortified outposts still surviving in Europe, and the best preserved. It is a moated cylindrical brick structure with an inner courtyard 24.4 meters in diameter, and seven turrets. Its 3-meter-thick walls hold 130 embrasures. The barbican was originally linked to the city walls by a covered passageway that led through St. Florian"s Gate and served as a checkpoint for all who entered the city.
On its eastern wall, a tablet commemorates the feat of a Kraków burgher, Marcin Oracewicz, who, during the Bar Confederation, defended the town against the Russians and shot their Colonel Panin. Masterpiece of medieval military engineering, with its circular fortress, was added to the city"s fortifications along the coronation route in the late 15th century.
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.
