Visingso

Visingsö is an island in the southern half of the lake Vättern in Sweden.
Visingsö lies 30 km north of the city Jönköping and 6 km west of Gränna from which two car ferries connects the island. The island is 14 km long and 3 km wide, with a total area of 24 km².
According to legend, a giant named Vist created Visingsö by throwing a lump of soil into the lake so that his wife could use it to step over the lake.
In the 12th and 13th century, Näs Castle on the southern end of Visingsö was the residence for the fragile Swedish monarchy.
