Ostrzeszów castle, situated at a short distance north-west of the town’s centre and probably originally separated from it by a moat, constituted an independent fortified establishment, although it was associated in the old times with the town’s fortification system. Built around mid-14th century, the endowment of King Casimir the Great, it was part of the ruler’s large-scale construction venture aimed at reinforcing the State’s borderline area.
Situated on a small, possibly artificially heaped-up hill, it once formed an installation embracing a rectangular area of ca. 27 m x 30 m, surrounded with tall brick walls, supported and reinforced on the angles with buttresses. In its south-eastern line – that is, on the town’s side – an enormous tower has been built, quadrilateral on its basement, turning into an octagon in its higher sections. By the tower, at its southern side, there was an entrance gate opening toward an extensive wall-surrounded courtyard. The courtyard’s inner developments were originally wooden and were replaced by brick structures around mid-15th century. A brick one-tract two- or three-storey building, rectangular in its projection, probably covered with a tall roof, was erected then along the yard’s north-western side, opposite the gate.
The castle developments so formed were meant to exercise a fortified/defensive function, in the first place, along with an administrative and residential function; they were the seat of consecutive castle-town starosts who represented the royal authority in the province. The castle was destroyed during the Swedish invasion, but was rebuilt afterwards in as early as 1661. Although it lost its defensive function, still being the seat of starost, it continued to be a centre of authority, also as home to magistrates’ and land courts.
Toward the end of 18th century, the castle’s walls and buildings were much neglected, and by mid-19th c., their condition threatened with construction disaster and the decision to have it demolished was made.
Relicts of perimetric walls and the tower (renovated and preserved in 1960) have survived till this day – the tower being made of bricks, founded on a square projection, on combined stone-brick foundations, turning into an octagon at a height of ca. 11 m above the area’s surface. Its brick elevations, with a gothic strand of the walls, have preserved remnants of former architectonic décor, in the form of a double ogival blind window in the upper section of the front wall.
Presently, the tower houses a display of torture appliances of yore, its top part offering a beautiful view of the town. For a tourist group, in order to use the tower, it is advised to contact the Regional Museum beforehand.
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.
