In 1888 on 25 June, strong wind and dry conditions contributed to two city fires in Sweden on the same day. On this day both Umeå and Sundsvall caught fire. The Sundsvall fire was the largest in Sweden's history. It is presumed that the fire was caused by a spark from a steamship. After the fire, and unlike Umeå, the decision was to rebuild using stone. Sundsvall's centre was later nicknamed Stenstaden ("the stone city"). One advantage of the new construction was that within three years the town was arguing that it should be allowed reduced insurance as new rules had been brought in that applied to wooden towns. One disadvantage was that after the fire only the better off could afford to live in the centre.
