The main tower and a secondary tower of Nuraghe Oes contain a single room, which was once divided into three spaces with wooden garrets supported by recesses, attached thanks to holes made in the walls.
Dating back to a period between the Bronze Age and the Iron Age (9th-6th century BC), the Oes is a majestic work of Nuragic architecture, built using well-finished basalt rocks. The main building consists of a tower (keep) with three floors and a truncated cone shape that ‘falls’ on all sides with a uniform slope. It is made up of 29 rows of stones. It is 16 metres tall and has a diameter of 11 and a half metres, making it the largest Nuragic building found so far. It once had a tholos vault (false dome). Against it, there is a bilobed bastion, with a perimeter of 50 metres, on two levels and with two entrances, that encloses a courtyard and two secondary towers. One of these is well-preserved. The overall complex measures 425 square metres and also includes a sacred area, with a fence (temenos) that has a vaguely hexagonal shape and a little megaron temple, the remains of a Tomb of Giants, of which you will notice the stele resting on the ground, a vast residential settlement of circular and oval huts. Their type is uncertain (perhaps cisterns and a second little temple). Between the sacred area and the Nuraghe, twenty rocks laid on edge and fixed in the ground resemble a megalithic circle.
References:Ogrodzieniec Castle is a ruined medieval castle originally built in the 14th–15th century by the W³odkowie Sulimczycy family. Established in the early 12th century, during the reign of Boles³aw III Wrymouth, the first stronghold was razed by the Tatars in 1241. In the mid-14th century a new gothic castle was built here to accommodate the Sulimczycy family. Surrounded by three high rocks, the castle was well integrated into the area. The defensive walls were built to close the circuit formed by the rocks, and a narrow opening between two of the rocks served as an entrance.
In 1470 the castle and lands were bought by the wealthy Cracovian townsmen, Ibram and Piotr Salomon. Then, Ogrodzieniec became the property of Jan Feliks Rzeszowski, the rector of Przemy¶l and the canon of Cracow. The owners of the castle about that time were also Jan and Andrzej Rzeszowskis, and later Pilecki and Che³miñski families. In 1523 the castle was bought by Jan Boner.
