Cracow proves to be Poland’s prime tourist attraction with hardly any equal in the entire Central Europe. The place has been selected at least since the Stone Age. Tradition assigns the foundation of Cracow to the mythical Krak, a Polish prince, about A.D. 700. In 1257 the city received the Magdeburg rights from Prince Bolesław V. The Old Town district is actually the medieval city established at that time. The well preserved original grid of streets with a wide central square, the largest in Europe, seems to be the last stage in the perfection of city-planning in the Middle Ages. Because of its unique value to humanity Cracow’s Historic Centre was among twelve properties entered in the first Unesco's World Heritage List publicized in 1978 (http://whc.unesco.org/en/list/). Presently, Cracow is one of the main cultural and educational centers of Poland.
