What is "vinterviken"

Vinterviken ("Winter-cove") is a bay in the Mälaren lake in southern Stockholm, Sweden. Vinterviken is located in a valley surrounded by the Gröndal and Aspudden suburb areas. The origin of the name Vinterviken can be traced back to the 17th century. Back then a common winter route (on the lake ice) used to go from Fittja and the Mälaren islands, and entered the city through Vinterviken and lake Trehörningen (nowadays named Trekanten).
