Many historically significant moments have taken place in the Minorite monastery over the past 800 years—the winter refectory hosted the wedding banquet of John of Luxembourg and Elizabeth of Bohemia. The summer refectory on the first floor, which is the largest hall among European monasteries, was the College of St. Bonaventure, but also the mother of the emerging National Museum in 1818. The emperor Charles IV also stayed here. In the second winter refectory, the Hall of Eliška Přemyslovna, the monastery thanked the butchers' guild for saving the monastery (St. James is the patron saint of butchers).
