Ladoga skerries are often compared with Norwegian fjords, it is interesting that the word "skerries" itself comes from the Norwegian skjær - "rock in the sea". Skerries are straits and bays between the coast and the islands, but under the name Ladoga Skerries, they usually mean the entire territory with an unusual relief, including the archipelago of uninhabited islands. In fact, the correct name for the empty rocky islands is luds.
