According to chronicler Jan Długosz, Saint Mary's Bacilica in the Main Square in Kraków was founded in 1221–22 by the Bishop of Kraków, Iwo Odrowąż. The building was destroyed during the Mongol invasion of Poland. Between 1290–1300 the new early Gothic church was built on the remaining foundations. It was consecrated twenty years later, in 1320.The church was completely rebuilt during the reign of Casimir III the Great between 1355 and 1365 with substantial contributions from wealthy restaurateur Mikołaj Wierzynek.The presbytery was elongated and tall windows added. The main body of the church was completed in 1395–97 with the new vault constructed by master Nicholas Werhner from Prague.However, the vault over the presbytery collapsed in 1442 due to a possible earthquake, which has never happened before nor since in Kraków.
