The Great Fire of Copenhagen in 1728 was the largest fire in the city's history, destroying nearly half of Copenhagen, including its medieval core and invaluable university libraries. This disaster had a profound impact on the city's architecture and urban planning, leading to significant rebuilding efforts. The fire also highlighted the need for improved fire safety measures and urban infrastructure in rapidly growing cities.

The Great Fire of Copenhagen in 1728 resulted in the loss of ancient Icelandic sagas and manuscripts, devastating Scandinavian scholarship. This prompted a movement to record and reconstruct national oral poetry, as poets sought to preserve their cultural heritage in the face of destruction.
