Mikkeli

The earliest signs of human life in Mikkeli are the Astuvansalmi rock paintings in Ristiina, dating back to 4100-2000 BCE. The Astuvansalmi is the largest rock painting site in the Nordic countries.

The peace treaty of Nöteborg in 1323, with which the pogost (church parish) of Savilahti was transferred from the control of Novgorod to Sweden, is the oldest written record of the settlement in the present region of Mikkeli. The locality received its present name Mikkeli after Archangel Michael by the early 16th century at the latest.

On 23 January 1597, more than 200 peasant rebels were killed in the parsonage of Kenkävero in part of the larger Cudgel War. In the war waged by King Gustav III of Sweden against Russia, the Battle of Porrassalmi took place a few miles south of Mikkeli on 13 June 1789. In the battle the Swedes (Finns) victoriously defended their positions against superior numbers of Russians.

Mikkeli was granted town rights in 1838. The provincial government of the province of Mikkeli that had been established in 1831, moved from Heinola to Mikkeli in 1843.

In 1918, during the Civil War, the headquarters of the White Army were established in Mikkeli. Mikkeli was located in a conservative farming area and it was a White stronghold, but elements of the Russian Army garrison in the area supported the Reds. A major engagement was fought around the railway station at Mäntyharju, about 20 km (12 mi) to the south of Mikkeli, when the Whites blocked a Red thrust coming north out of Kouvola. During the Winter War and Continuation War, the headquarters of the Finnish Army was located in Mikkeli. The Army staff made their base in a local secondary school. At the site of that school is the small Päämajamuseo (Finnish for 'Headquarters Museum') containing photographs and memorabilia of the era. As a result of serving as the headquarters of the army that was based there, Mikkeli was bombed heavily, but since there was almost no high-rise development at the time the damage was quickly repaired. Architecturally, most of pre-war Mikkeli doesn't exist anymore.

Wartime Mikkeli is identified with Marshal C. G. E. Mannerheim, the supreme commander of the Finnish Defence Forces and later President of Finland. His personal railway carriage, which he used as a command post during the war, is parked in a siding at Mikkeli Station. It is possible to look inside the carriage through its windows at any time, but public entry to the carriage is permitted only once a year, on Mannerheim's birthday (4 June). The carriage was the venue of Mannerheim's famous 1942 meeting with Hitler near Immola, during which their private conversation was secretly recorded; photographs of this meeting are on display in the carriage. Mannerheim was a regular diner at the Mikkelin Klubi, where his favourite drink was schnapps.

One of the main museums in the town is the Jalkaväkimuseo (Finnish for 'Infantry Museum'), located in one of the former army barracks, close to the University of Applied Sciences. It contains exhibits from the four wars in Finland's modern history – the Civil, Winter, Continuation and Lapland Wars. The museum also contains an exhibit dedicated to Finnish war hero Lauri Törni.

In 1986, there was a hostage crisis in Mikkeli when a bank robber drove from Helsinki with three hostages and parked there. When the police shot at the hostage taker's car he detonated explosives contained inside, killing himself and one hostage.
