Great Fire of Turku

The Great Fire of Turku ( _fi. Turun palo and _sv. Åbo brand) was a conflagration that is still the largest urban fire in the history of Finland and the Nordic countries. The fires started burning on September 4, 1827 in Burgher Hellman’s house on Aninkaistenmäki slightly before 9 p.m. The fire quickly swept through the northern quarter, spread to the southern quarter and jumped the Aura River, setting the Cathedral Quarter on fire before midnight. By the next day, the fire had destroyed 75% of the city. Only 25% of the city was spared, mainly the western and southern portions.The fire destroyed the historical downtown area of Turku, including Turku Cathedral and the main building of the Imperial Academy of Turku, Akatemiatalo, which were badly damaged. The city's population suffered many casualties and the damage was considerable and was felt for a long period of time in the aftermath of the event.

The night of the fire, Friedrich Wilhelm Argelander, Observator at the Imperial Academy of Turku, was in the Vartiovuori Observatory on Vartiovuorenmäki. Due to the fire, he had to stop what he was doing. In his observation log, he wrote: "Tässä keskeytti havainnot hirveä tulipalo, joka pani Turun tuhaksi." (Today observation was interrupted by a horrible fire that reduced Turku to ashes.”) The observatory, placed on the top of a tall hill, was spared though and work was continued on September 9. As the rest of the academy has suffered great damage, its indispensable activities such as meetings of the consistory and the Chancellor’s Office, were moved to the observatory. Most of Finnish archives, including practically all material from the Middle ages, was destroyed in the fire.

At the time of the fire, Turku was, and for some time afterwards, too, the largest city in Finland, which is why the Great Fire of Turku was a major national disaster. As a result of the fire, the Imperial Academy of Turku was transferred to Helsinki, the new capital of the Grand Duchy of Finland, thus contributing to the city losing its significance as Helsinki grew.

Governor-General of the Grand Duchy of Finland Arseniy Zakrevskiy was responsible for rebuilding the city after the fire. His proposal resulted in the Senate of Finland selecting Architect Carl Ludvig Engel to create the new city plan for Turku. Downtown Turku is still based on Engel’s grid plan, which was approved on December 15, 1828. The largest buildings in downtown Turku, the cathedral and Akatemiatalo, were refurbished, and some of the other buildings, such as the Old Town Hall and the former sugar factory were rebuilt. The majority of the city, however, had to be completely rebuilt. Turku’s grid plan design had a significant influence on how other Finnish towns were laid out.

The Cloister Hill area, which was completely spared due to its location on the outskirts of the area hit by the fire, was protected and opened up as a handicrafts open-air museum in 1939.
