Each year in May the Jagiellonian University marks the anniversary of its foundation by King Casimir the Great in 1364. The occasion, known as the Jagiellonian University Day, begins with flower laying ceremony at the tombs of the University’s founders: King Casimir the Great, Queen Jadwiga and King Vladislaus Jagiełło at Wawel Cathedral. It was the second university to be founded in Central Europe, after the one in Prague in 1348. After the period of decline following the death of its founder, the University was restored owing to the endeavours of Queen Jadwiga, who pleaded its case to the Pope in Avignon and later bequeathed her personal effects to the University, which was re-established in 1400 by Jadwiga’s husband Vladislaus Jagiełło, after the benefactress's premature death.
