Copenhagen lost around 22,000 of its population of 65,000 to the plague in 1711. The city was also struck by two major fires that destroyed much of its infrastructure. The Copenhagen Fire of 1728 was the largest in the history of Copenhagen. It began on the evening of 20 October, and continued to burn until the morning of 23 October, destroying approximately 28% of the city, leaving some 20% of the population homeless. No less than 47% of the medieval section of the city was completely lost. Along with the 1795 fire, it is the main reason that few traces of the old town can be found in the modern city.
