Château-d'Œx (French pronunciation: [ʃɑto dɛ]) is a municipality in the canton of Vaud in Switzerland.

The lack of iron ore and the sparseness of the soil probably prevented the romanization of lowland valleys.

At the beginning of the 14th century, the castle at La Motte was rebuilt for the Counts of Gruyere.

After clearing the woods, the region was intensively farmed and produced barley, hay, hemp and cheese.

Then, in 1403, against the wishes of the Count of Gruyères, the villagers joined a limited alliance with Bern.

The alpine pastures were leased to private cheesemakers, who there produced Gruyère cheese.

[3] In 1849, the Institute Henchoz opened as a preparatory gymnasium, which replaced the older Latin school.

Cheese was no longer allowed to be carried across the mountains but was now transported on local draft horses.

Due to customs taxes with the neighbouring Canton of Fribourg, cheese was carried on a route over the Col de Chaude to Villeneuve (VD) and from there to the shores of Lake Geneva, without crossing the Fribourg border.

Changes in markets and improvements in animal husbandry led to more Simmental cattle being raised for meat rather than cheese production.

The opening of the Montreux–Lenk im Simmental line in 1904 made Château-d'Œx an attractive summer resort.

Other infrastructure included the suspension bridge at Turrian (1883), a swimming pool and a campsite (1932), a cable car (1945) and the Pont du Berceau (1945).

Hot air balloons and river rafting became common in the summer, while local crafts, sawmills and gravel mining are the main branches of the industrial sector.

BIS President Thomas H. McKittrick and economic adviser Per Jacobsson moved into the nearby château of Rougemont, while the rest of the staff found accommodation in the village.
