In 1815, the funeral of Prince Józef Poniatowski took place at Wawel Cathedral. Since that event, national heroes have been entombed within the cathedral; prior to this date, only bodies of monarchs were interred there. In 1818, the body of national hero Tadeusz Kościuszko was buried in St. Leonard's Crypt. During the reconstruction of Potocki Chapel in a classical style, the statue of Prince Arthur Potocki by the Danish sculptor Bertel Thorvaldsen was placed within the chapel. A second work by Thorvaldsen was placed in Queen Sophia's Chapel.
