An excerpt from the article 27 facts about Tallinn

This is the oldest part of Tallinn, where most of the buildings were built in the 13th and 14th centuries. Its area is 113 ha and the buffer zone is 2253 ha. Tallinn's Old Town has managed to fully retain its structure as a medieval Hanseatic city, intact since the 13th century. It borders the walls of Tallinn.

During the Soviet bombings in 1944, approximately 10% of the Old Town buildings were destroyed.
