All Saints Church is surrounded by a castle-wall-type barrier - by the wall of the former cemetery. The residents of the valley of the Tettye river built a one-navy church here as early as the 13th century. The originally Romanesque style All Saints Church was reconstructed in the 15th century in Gothic style. The exterior is simple, while a short tower stands on the triangular pediment of the main façade. The interior is mostly 18th century Baroques style. During the Turkish occupation this was the only church that still belonged to the Christians. It was used jointly by Catholics, Calvinists and Unitarians. This is where the famous religious dispute of the Calvinist Máté Skaricza and the Unitarian György Válaszúti took place in 1588.
The church became Unitarian by the mid-17th century, the Catholics only managed to regain it in 1664. Following this period, it was under Jesuit management until 1704. At this time it was reconstructed to be a three-nave church, this is when the little tower was added. On the south side of the cemetery, protected by stone wall, 18th-19th century graves, on the north, Baroques graves can be found.
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.
