The Giants' grave of Su Mont'e s'Abe is an archaeological site located in the municipality of Olbia. Like other giants' tombs of Gallura, it was built in two main phases of construction. In the first stage, during the period of the Bonnanaro culture, it was built an allée couverte tomb; later, in the second phase, during the age Nuragic age (1600 BC approximately), the allée couverte was transformed into a giants' tomb with the realization of the exedra and the erection of the central stele of which few traces remain today.
The tomb, which measures about 28 meters in length and six in width, was excavated and restored in the 1960s.
References:The Beckov castle stands on a steep 50 m tall rock in the village Beckov. The dominance of the rock and impression of invincibility it gaves, challenged our ancestors to make use of these assets. The result is a remarkable harmony between the natural setting and architecture.
The castle first mentioned in 1200 was originally owned by the King and later, at the end of the 13th century it fell in hands of Matúš Èák. Its owners alternated - at the end of the 14th century the family of Stibor of Stiborice bought it.
The next owners, the Bánffys who adapted the Gothic castle to the Renaissance residence, improved its fortifications preventing the Turks from conquering it at the end of the 16th century. When Bánffys died out, the castle was owned by several noble families. It fell in decay after fire in 1729.
The history of the castle is the subject of different legends.
