# Albula/Alvra

Albula/Alvra is a municipality in the Albula Region in the canton of Graubünden in Switzerland. On 1 January 2015, the former municipalities of Alvaschein, Mon, Stierva, Tiefencastel, Alvaneu, Brienz/Brinzauls, and Surava merged to form the new municipality of Albula/Alvra.

## History
### Alvaschein

The first mention of the municipality came in 1154, on the occasion of the construction of nunnery named Alvasinis. It became subordinate to the Princes-Bishop of Chur in 1282. In 1367, it belonged to the municipality of Gotteshausband. The inhabitants finally bought their freedom from the Princes-Bishop in 1732. Nearly the whole community was destroyed in a fire in 1745. It has been the seat of the district of the same name since 1851.

### Mon

Mon is first mentioned around 1001-1200 as de Maune. In 1281, it was mentioned as Mans. Until 1943, Mon was known as Mons.

### Stierva

Stierva is first mentioned in 841 Seturiuo. Until 1943, Stierva was known as Stürvis.

### Tiefencastel

Tiefencastel is first mentioned in 831 as in Castello Impitinis. Starting around in the 14th century, it was known as Tüffenkasten.

### Alvaneu

Alvaneu is first mentioned in 1244 as Aluenude. In 1530, it was mentioned as Allweneü. On 20 March 2007, Peter Martin Wettler, a media expert and resident of Zurich was appointed Prince of Belfort by the village's authorities. He was to serve for one year with a mandate to improve tourism and the local economy.

### Brienz/Brinzauls

Brienz/Brinzauls is first mentioned around 840 as Brienzola.
By the 12th century, the village was an economic center for the Bishop of Chur. The Lords of Brienz were first mentioned as the owners of a fortified tower in the village in 1259. The tower fell in ruin and was demolished in 1880. Until 1851, the village was part of the Herrschaft of Belfort. Between 1869 and 1883, Brienz/Brinzauls and Surava were united into a single political municipality. In 1874, a fire damaged or destroyed much of the village.
The village church was first mentioned in 840. In 1519 St. Calixtus became the patron saint of this church. In 1526, it separated from the parish of Lantsch/Lenz to become a parish. In 1725, Surava separated from Brienz/Brinzauls to form its own parish.
In 1870-73, the Landwasserstrasse was built which helped connect the village to the rest of the country. Beginning in the 1960s, the number of local farmers began to drop, however agriculture still remains important. In 1990, about 43% of all jobs in the municipality were in agriculture. In 1860, the entire population spoke Romansh. By 1990, it had dropped to only 58%.
On 9 May 2023, all residents were ordered to evacuate the village due to the determination by geologists that 2,000,000 cubic metres (71,000,000 cu ft) of rock from the mountain above was expected to collapse into the valley that includes the village. At that time, the population of the village was less than 100 residents. A researcher at the University of Cambridge attributed the impending collapse, expected within a week to 24 days, to climate change that is driving glacier melt in the Alps. Simon Löw, emeritus professor of Engineering Geology at ETH Zurich, disputed a link to climate change, citing the lack of thawing permafrost and any correlation between annual rainfall and the speed at which the slope slides. On the night of 15 and 16 June, a major rockfall occurred, stopping short of the village. Municipal officials ended the evacuation of the village on 3 July, while emphasizing that future evacuations could remain necessary.

### Surava

Surava is first mentioned about 1580 as Surraguas.
