History
During the Finnish occupation in the Continuation War (1941–1944), the city was styled as Äänislinna (or Ääneslinna), rather than the traditional Petroskoi. This name was a literal translation of Onegaborg, the name of a settlement marked on a 16th-century map by Abraham Ortelius near the present-day city, Ääninen being the Finnish toponym for Lake Onega. On 14 October 1941, the Finnish authorities opened the first concentration camp. By the recapture of Petrozavodsk there were 11 concentration camps.
