Kraków - Bazylika Bożego Ciała

A legend attributes Kraków's founding to the mythical ruler Krakus, who built it above a cave occupied by a dragon, Smok Wawelski. The first written record dates to 965, when Kraków was described as a notable commercial center captured by a Bohemian duke Boleslaus I in 955. The first ruler of Poland, Mieszko I, took Kraków from the Bohemians.

In 1038, Kraków became the seat of the Polish government. By the end of the 10th century, the city was a center of trade. Brick buildings were constructed, including the Royal Wawel Castle. The city was sacked and burned during the Mongol invasion of 1241. It was rebuilt and incorporated in 1257 by Bolesław V the Chaste who introduced city rights. In 1259, the city was again ravaged by the Mongols. The third attack in 1287 was repelled thanks in part to the newly built fortifications.

The city rose to prominence in 1364, when Casimir III founded the University of Kraków, the second oldest university in central Europe. But after Casimir´s death in 1370 the campus did not get completed.

As the capital of the Kingdom of Poland and a member of the Hanseatic League, the city attracted craftsmen from abroad, guilds as science and the arts began to flourish. The 15th and 16th centuries are known as Poland's "Złoty Wiek" (Golden Age).

After childless King Sigismund II had died in 1572, the Polish throne passed to Henry III of France and then to other foreign-based rulers in rapid succession, causing a decline in the city's importance that was worsened by pillaging during the Swedish invasion and by an outbreak of bubonic plague that left 20,000 of the city's residents dead. In 1596, Sigismund III of the House of Vasa moved the capital of the Polish–Lithuanian Commonwealth from Kraków to Warsaw.

The Corpus Christi Basilica was founded around 1340 by Casimir III the Great as a parish church in Kazimierz, a new town built on an island on the Vistula south of the Old Town. The church was expanded in 1385 in the brick Gothic style by the master builders Mikołaj Czipser and Jan Czipser. In 1405 Ladislaus II Jagiełło brought canons from an Augustinian canonry in Bohemia to build an Augustinian canonry in Kazimierz.
