In 1978, Karol Wojtyła, archbishop of Kraków, was elevated to the papacy as Pope John Paul II—the first non-Italian pope in 455 years. Also that year, UNESCO approved Kraków's entire Old Town and historic centre as its first World Heritage List alongside Quito. Kraków is classified as a global city with the ranking of "high sufficiency" by the Globalization and World Cities Research Network. Its extensive cultural heritage across the epochs of Gothic, Renaissance and Baroque architecture includes the Wawel Cathedral and the Royal Castle on the banks of the Vistula, the St. Mary's Basilica, Saints Peter and Paul Church and the largest medieval market square in Europe, the Rynek Główny. Kraków is home to Jagiellonian University, one of the oldest universities in the world and traditionally Poland's most reputable institution of higher learning.
