Gásadalur is located on the west-side of Vágar and is enjoying the view over the island Mykines.
The village has been in danger of depopulation.
In early 2004 a tunnel was blasted through the mountains so the village is now connected to the road network of the island.
I 1940 a stairway was built from the beach up to the village that is located high on the island.
Gásadalur is named after its founder a lady called Gasa. She was a rich woman who lived in Kirkjubo in the 12th. century. She owned half of Streymoy (the largest island) but when it was revealed that she had had meat for dinner in fast she lost all her properties to the church. After this she moved to Vágar.
Tradition says that a rock in Gásadalur is occupied by dwarfs.
A poor peasant who had been out fetching peat came by the rock one day. The rock was open and from outside he saw that the dwarfs were forging tools inside the rock. He was curious and sneak closer to watch them. Out came a dwarf. "Cheeky were You, poor as You are, even so this knife is now Yours" it said and threw out a knife to the man. The knife was so sharp that it could cut anything regardless of how hard it was.
