Helsinki — Continuation War Enigma
You are President Risto Ryti's diplomatic advisor, on a secret mission in 1942 Helsinki.
Your task is to reconstruct the negotiations that led Finland to ally with Germany
Dive into the diplomatic secrets of the Continuation War (1941-1944) through Helsinki's government palaces and monuments where Finland's controversial alliance with Nazi Germany was forged.
The story that haunts this land
Helsinki becomes the stage for secret negotiations in 1941 when Finland must choose sides facing Soviet invasion. On Senate Square, laid out from 1816 under Russian rule, stand the government buildings that would house debates about the German alliance. The Lutheran cathedral, consecrated in 1852 by Carl Ludvig Engel, dominates with its 63-meter height this 200-meter square where Finns gathered during the war. You begin your investigation where Russian neoclassical architecture still testifies to the first foreign occupation Finland wants to avoid reliving.
The Government Palace, built in 1808 as the Russian Senate seat and completed by Engel in 1822, becomes the nerve center of Finnish military decisions. Within these walls occupied by Russian authorities until 1917, Continuation War operations are coordinated. President Ryti receives German and Soviet emissaries here, weighing each alliance. History's irony has this palace, symbol of Russian imperial domination, now serving to organize resistance against the USSR alongside Nazi Germany.
The Bank of Finland, built in 1883 by Sebastian Gripenberg in neo-Renaissance style, manages Finland's war economy during the conflict. This protected historic building conceals the financial negotiations of the German-Finnish alliance. Nearby, Marshal Mannerheim's equestrian statue, inaugurated in 1960, commemorates the supreme commander who led Finnish forces from 1941 to 1944. Standing 5 meters high and weighing 12 tons, this work by Aimo Tukiainen on Mannerheimintie boulevard recalls the man who negotiated with Hitler while keeping his distance.
The Finnish Parliament, built between 1927 and 1931 by Alvar Aalto with 28,000 tons of granite and 200 columns, becomes the theater for debates on the Nazi alliance. Inaugurated March 2, 1931 by President Svinhufvud, this Eduskuntatalo houses parliamentary sessions that ratify military cooperation with Germany. Deputies vote on emergency laws and war budgets, transforming this Nordic democracy into a de facto ally of the Third Reich to reconquer Karelia lost to Stalin.
Your journey ends at the Presidential Palace, Risto Ryti's residence during the Continuation War. Built between 1814 and 1845 as the Russian imperial Senate palace, restored between 1982 and 1986 for 250 million marks, this building symbolizes Finnish dilemmas. Ryti signs the secret agreement with Ribbentrop here in June 1944, committing not to conclude separate peace with the USSR. Eliel Saarinen's Central Station, opened in 1919 and logistics hub for 23 million passengers, reminds you this diplomatic war was also played out in troop transports. You leave understanding a Finland caught between two totalitarianisms, forced to choose the lesser evil.
