It developed as a major centre of the Hanseatic League, and its wealth is demonstrated by the opulence of the public buildings (the churches in particular) and the domestic architecture of the merchants’ houses, which have survived to a remarkable degree despite the ravages of fire and war in the intervening centuries.” was the description of UNESCO when Tallinn´s Historic Centre was placed on the World Heritage List in 1997.
