The estate was first mentioned in 1466. It has been associated with the Gilsens, von Rosens, von Zoeges, von Benckendorffs, von Krusensterns and von Uexküll-Güldenbandts. The ruins of a vassal castle destroyed during the Livonian War were reconstructed as a stately castle in the 17th to 18th centuries, which received its present form in 1790.
For many years, the manor was the home of a world famous explorer and mariner Adam Johann von Krusentern, who also passed away in Kiltsi. Since the 1920s, the manor houses a school. The building has been thoroughly restored starting in 2000.
the mansion can be rented for celebrating birthdays and weddings, organizing trainings and seminars, and in summer you have the opportunity to visit the mansion.
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.
