The first building was constructed after 1272, following the consecration of the cathedral. Its current appearance dates back to the Baroque redesign of 1732/33 under Bishop Joseph von Rost, a Tyrolean native (serving as Bishop of Chur as Benedikt von Rost from 1728 to 1754), who incorporated architectural ideas from his homeland into the building. The cookbook "Ein schön Kochbuch 1559" (A Beautiful Cookbook 1559) was created in the Episcopal Palace between 1559 and around 1610. It is considered the oldest cookbook in Switzerland. In 2020, the Cathedral Treasury Museum, featuring the cathedral treasury and the death pictures dated 1543, will open in the Episcopal Palace.

Ruinaulta Rhine Gorge The Ruinaulta, or Rhine Gorge, is a gorge of the Vorderrhein River, up to 400 meters deep and approximately 13 kilometers long, between Ilanz and the mouth of the Hinterrhein River near Reichenau in the canton of Graubünden in Switzerland. The Romansh name 'Ruinaulta' is composed of the two words ruina (scree slope, quarry) and aulta (high). The Ruinaulta was formed after the Flims Landslide almost 10,000 years ago. At that time, over 10 billion cubic meters of rock broke off between the Flimserstein and Piz Grisch, burying the Vorderrhein Valley between the present-day villages of Castrisch and Reichenau under a mass of debris several hundred meters thick. Because the Vorderrhein River could no longer drain away, a lake was dammed over a length of approximately 25 kilometers. Over time, the river cut deep into the landslide, and the resulting lake drained away completely. What remained was the Ruinaulta, with its steep limestone scree cliffs in impressive erosion formations. Text / Source: Wikipedia https://de.wikipedia.org/wiki/Ruinaulta

Confluence of the Vorderrhein and Hinterrhein, Reichenau Dominated by Reichenau Castle, the hamlet lies at the confluence of the Vorderrhein and Hinterrhein rivers, making it virtually the birthplace of the Rhine. It all began 10,000 years ago. Between the Flimserstein (a high plateau) and Piz Grisch, over 10,000 cubic meters of rock broke off and thundered down into the valley. Towards Reichenau, the Vorderrhein valley disappears under a gigantic mass of rubble. From there, the Rhine diligently ate its way through the rock, creating the spectacular Swiss "Grand Canyon" – the Ruinaulta.
