Grodno Castle (formerly Kynsburg) is a castle located in the southern parts of the Wałbrzych Mountains, on the Choina Mountain (450 metres), standing to the left of the river Bystryca. The valley of this river, formerly known as the Silesian Valley, creates a natural boundary between the Owl Mountains and to the west of it the Wałbrzych Mountains. The castle is located in Zagórze Śląskie (11 km east of Wałbrzych), Lower Silesian Voivodeship in Poland.
The picturesque location of the castle is exacerbated by the barraged Lubachowskie Lake in the foothills of the mountain.
According to tradition the castle was built in 1193, by Duke Boleslaw I the Tall. The castle, together with a network of fortresses was used as a defense line between the Duchy of Jawor and the Kingdom of Bohemia. In the sixteenth century Grodno Castle was expanded by a gatehouse, on which there is precious sgraffito, and a sundial clock from 1716. The castle was devastated in battles against the Swedes during the Thirty Years' War, slowly falling into ruins. In the nineteenth century the tower had collapsed. The last owner of Grodno, was the Zedlits family, which had continued renovation works and strengthened the castleReferences:
The Castle of Gruyères is one of the most famous in Switzerland. It was built between 1270 and 1282, following the typical square plan of the fortifications in Savoy. It was the property of the Counts of Gruyères until the bankruptcy of the Count Michel in 1554. His creditors the cantons of Fribourg and Bern shared his earldom. From 1555 to 1798 the castle became residence to the bailiffs and then to the prefects sent by Fribourg.
In 1849 the castle was sold to the Bovy and Balland families, who used the castle as their summer residency and restored it. The castle was then bought back by the canton of Fribourg in 1938, made into a museum and opened to the public. Since 1993, a foundation ensures the conservation as well as the highlighting of the building and the art collection.
The castle is the home of three capes of the Order of the Golden Fleece. They were part of the war booty captured by the Swiss Confederates (which included troops from Gruyères) at the Battle of Morat against Charles the Bold, Duke of Burgundy in 1476. As Charles the Bold was celebrating the anniversary of his father's death, one of the capes is a black velvet sacerdotal vestment with Philip the Good's emblem sewn into it.
A collection of landscapes by 19th century artists Jean-Baptiste-Camille Corot, Barthélemy Menn and others are on display in the castle.
