The Gannarve grave is outlined by large standing stones, forming the shape of a ship. It has been built at the end of the Bronze Age, about 1100 – 500 B.C. The grave is 29 metres long and 5 metres wide. It is only one of about 350 boat-shaped graves on the island. In most cases, only one burial has been uncovered in each grave. When these people were buried, it was a custom to cremate the dead on a pyre. After cremation, the bones were crushed and washed before they were placed in an urn.
There were once two boat-shaped graves here at Gannarve. One of them fell victim to the plough long ago. The existing grave was almost destroyed in the same way. Only the stem stones remained when archaeologists started excavating the monument in 1959. The excavation uncovered soil marks of all the removed stones beneath the peat. Consequently, the reconstruction of the entire grave was not too diﬃcult.
There were plenty of large stones lying right next to the grave, and it is quite possible that several of the stones used once actually belonged to the original grave.
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.
