The story that haunts this land

Your quest for the Great Book begins in Place du Bourg, the starting point for cheese fairs since the 13th century. In front of the 1620 fountain, you imagine the weekly Gruyère cheese markets that were held there as early as 1394, surrounded by listed 17th-century buildings. This historic site, the capital of Gruyère AOC cheese, was the beating heart of the trade that made the counts wealthy, and where the regional cheese monopoly you must protect was forged.

Continue to the Château de Gruyères, residence of the counts until 1555. Built in the 13th century, this Swiss historic monument, classified ISOS in 1980, houses 13 rooms open to the public over 2,500 m². It is here that Michel Mayor, official cheesemaker of the 20th century, would have drawn his inspiration to standardize Gruyère AOC. Since 1998, it also hosts the HR Giger Museum, offering a striking contrast between medieval heritage and contemporary art.

The Remparts de Gruyères, medieval fortifications built between 1280 and 1350, lead you along a 1.2 km protection of the medieval village. With 14 preserved watchtowers, the highest measuring 12 meters, these walls were restored in 1905 by the Swiss Society for the Conservation of Historic Monuments. They bear witness to the power of the local lords and their desire to defend a Fribourg cultural heritage vital for the cheese economy.

Rue du Bourg, the main paved thoroughfare from the 14th century, plunges you into the commercial heart of Gruyères. Approximately 300 meters long, it is lined with arcaded houses from the 15th-16th centuries bearing the escutcheons of influential cheese-making families. This ancient shopping street hosted the cheese market since 1360, a place where Josselin de Gruyère, 16th-century bailiff and administrator of the alpine pastures, would have overseen crucial exchanges for the development of local cheese.

Your journey concludes at the Grosse Porte de Gruyères, the main entrance built around 1380, 8 meters high with its original portcullis and machicolations. It bore the escutcheon of the Counts of Gruyère until 1555, symbolizing their power over this Swiss medieval village. As an archivist, you have not only discovered the history of this monopoly but also the efforts of men like Alexandre Cailler, a 19th-century chocolatier, who shaped the regional dairy economy and the heritage of Gruyères. Your exploration has allowed you to understand how this cheese destination became an intangible UNESCO site, revealing the deep connections between history, territory, and cheese.
