The capital of Estonia, Tallinn was called Reval until the 20th century. The port's ideal maritime position has always been a temptation to other nations and won it a position in the Hanseatic League. This cross-cultural history gives Tallinn a special ambience that visitors appreciate. The main attraction is the Old Town. Perched on a low hill by the shore, its fortification walls, worn cobbled streets and 13th-century buildings make it one of the purest medieval towns in all of northern Europe. With about a half-million inhabitants, Tallinn comprises almost a third of Estonia's population. Outside of town there is rich dairy land and along the coast stretch expansive sand beaches.
