Älvdalen
Älvdalen (literally means River Valley) is a locality and the seat of Älvdalen Municipality in Dalarna County, Sweden, with 1,810 inhabitants in 2010.
The parish is widely known for being the place of manufacturing, in 1839, of the 4-meter granite vase (called Älvdalen Vase), installed in the Summer Garden in Saint Petersburg (a gift from Charles XIV John of Sweden to Nicholas I of Russia).
It is also known for its dialect or language called Elfdalian, which along with innovations also preserves some Old Norse traits not preserved in most (other) Swedish dialects.
