All other reigning Grand Dukes and Grand Duchess and their spouses have been buried at Notre-Dame Cathedral, the Roman Catholic cathedral of Luxembourg City, Luxembourg. Originally built as a church by the Jesuits to serve as a place of worship for their college, the cornerstone was laid in 1613 and the church was consecrated and dedicated to the Immaculate Conception of the Virgin Mary in 1621. After the Jesuits had left Luxembourg City in 1773, Empress Maria Theresa of Austria gave the church to the city. The church received the name Notre-Dame (Our Lady, referring to the Virgin Mary) in 1848.  In 1870, when Luxembourg became an archdiocese and got an archbishop, Notre-Dame Church became Notre-Dame Cathedral. The cathedral underwent extensive expansion from 1935 – 1938.

Grand Duchess Marie-Adélaïde of Luxembourg, who reigned 1912 – 1919, was the first family member to be buried in the Ducal Crypt after she died of influenza in 1924 at the age of 29.  However, there are royal remains in the Ducal Crypt that are much older. In 1945, the remains of Jean of Bohemia, Count of Luxembourg, King of Bohemia and titular King of Poland, were removed from his burial place and reinterred with military honors in the Ducal Crypt of Notre-Dame Cathedral Luxembourg. Born in Luxembourg in 1296, Jean is famous for having died while fighting in the Battle of Crécy at age 50, after having been blind for a decade. He is considered a Luxembourg national hero.
