Tenna is a former municipality in the district of Surselva in the cantonofGraubündeninSwitzerland. The municipalities of Valendas, Versam, Safien and Tenna merged on 1 January 2013 into the new municipality of Safiental.[1]
Tenna is first mentioned in 1398 as Thena.[2] The significant incidence of hemophilia in the population was documented in the mid 1800s and then later (1909) referenced by Bulloch and Fildes in "Treasury of Human Inheritance."
The blazon of the municipal coat of armsisGules St. Valentin clad Argent and caped Or with his dexter raised in blessing and holding in sinister a crosier of the last. [3] The figure of Valentin von Rätien (an early bishop of Passau) comes from the municipal seal, where he is also represented as a seated figure.
Tenna had an area, as of 2006[update], of 11.3 km2 (4.4 sq mi). Of this area, 45.1% is used for agricultural purposes, while 34% is forested. Of the rest of the land, 1.1% is settled (buildings or roads) and the remainder (19.8%) is non-productive (rivers, glaciers or mountains).[4]
The former municipality is located in the Safien sub-district of the Surselva district. It is a German-speaking collection of small settlements on a terrace above the west side of the Safien Valley. It consists of the village of Tenna which is made up of the sections of Ausserberg, Mitte, and Innerberg as well as the hamlets of Acla and Egschi along the valley road.
Tenna is mostly in a tick-free / low-risk area.[5] However, as you move lower down to areas with higher humidity and warmer temperatures, such as the Rabiusa, the risk of ticks increases. Nearby municipalities, such as Versam, show up as hot (high-risk) in Switzerland's tick bite model.
The Swiss Reformed church in Tenna is listed as a Swiss heritage site of national significance.[6]
In February 2012, the world’s first solar-powered ski lift was completed in Tenna. It is 450 meters long and has the capacity to pull 800 skiers up the mountain per hour. The lift uses approximately 80 solar panels, which are expected to produce around 90,000 kWh of energy per year—of which only 22,000 kWh are required for the operation of the ski lift.[7] The excess power is sold to the grid.
As of 2011[update], Tenna has a population of 110[8]—recovering from a historical low of 79 in 2000.[2]
