Weinsberg castle was established on a mountain at the trade route running from Heilbronn to Schwäbisch Hall around the year 1000. In 1140 the castle was besieged by Konrad III in the course of the struggles between the Staufers and the Welfs. Finally it had to surrender on December 21, 1140, since the army of Welf VI to release the castle had been defeated by the Staufers in a battle. According to the report of the Chronica regia Coloniensis, the women of the castle were granted free departure and allowed to take what they could carry on their backs. They carried down their men, and so saved their lives, since the king adhered to his word. The women became known as treue Weiber ('loyal women'). The castle (today's ruin) is called Weibertreu due to this occurrence.
On April 16, 1525 (Easter Sunday), during the German Peasants' War, the peasants attacked and destroyed the castle, which was already damaged from an earlier attack in 1504. They then proceeded to execute the nobleman who had been in command of both town and castle and who had treated the peasants very badly several times before.References:
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.
