Old Town of Tallinn has managed to wholly preserve its structure of medieval and Hanseatic origin.

Old Town represents an exceptionally intact 13th century city plan.

[1] Since 1997, the area has been registered in the UNESCO World Heritage List.

[3] During World War II, while the German army occupied Estonia in 1941–1944, Tallinn Old Town suffered from several instances of aerial bombing by the Soviet air force.

During the most destructive Soviet bombing raid on 9–10 March 1944, over a thousand incendiary bombs were dropped on Tallinn, causing widespread fires, destroying about 10% of the buildings in the Old Town, killing hundreds, and leaving over 20,000 people without shelter.
