The Great Fire of Turku (Finnish: Turun palo and Swedish: 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 4 September 1827 in burgher Carl Gustav Hellman’s house on the Aninkaistenmäki hill 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.
