At the site Lonely Planet – Destination Norway, there is a piece of text about the village Å:

This fishing village on the Lofoten island of Moskenes is intriguingly named and well-preserved. It boasts a shoreline of red rorbu, plenty of cod drying on racks, and postcard-perfect scenes at every turn. Many of the village’s buildings have been set aside as the Norwegian Fishing Village Museum, complete with old boats and boathouses, a period bakery, storehouses and so on. Nearby is Moskenesstraumen, a maelstrom with a mighty whirlpool which inspired tales by Jules Verne and Edgar Allan Poe.
