The Gavrinis island is famous because of its important passage grave, a megalithic monument from the Neolithic period, belonging to the same broad context as the Breton megaliths of Carnac and Locmariaquer. At the time of its construction, c. 3500 BC, the island was still connected with the mainland. The rich internal decorations make Gavrinis one of the major treasuries of European megalithic art. The tomb is also remarkable for the care taken in its construction and its good preservation.
The stone mound has a diameter of about 50m. The mass of stones forming the cairn is internally structured by a series of walls, subdividing it into separate 'ranks'. It is a characteristic example of Neolithic dry stone architecture. The mound covers a single rectangular (nearly square) slab-built burial chamber, located at the centre of the mound and measuring about 2.5m across. The chamber is built of about 50 carefully placed slabs. The biggest of these is the ceiling slab which weighs nearly 17 tons.
The chamber is reached from outside by a 14m long corridor or passage. Of the 29 orthostat slabs that form the sides of the passage, 23 are decorated with carved symbols and patterns. Some of the symbols appear to represent non-abstract objects, like axes and croziers or staffs. A common horn-like motif may symbolise cattle, a shape conventionally called the shield may be a very stylised human figure. More abstract motifs include zigzag lines, lozenges and snake-like lines.
A replica of part of the Gavrinis passage with its decorated slabs can be visited in the Museum at the megalithic necropolis of Bougon.
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.
