 Built from its earliest nucleus outward, and having escaped much of the destruction endured by Poland during the 20th-century wars, Kraków's many architectural monuments can typically be seen in historical order by walking from the city centre out, towards its later districts.Kraków is one of the few medieval towns in Poland that does not have a historic Ratusz town hall in its Main Square, because it has not survived the Partitions of Poland.Kraków's historic centre, which includes the Old Town, Kazimierz and the Wawel Castle, was included as the first of its kind on the list of UNESCO World Heritage Sites in 1978.
