The cathedral "Notre-Dame" of Luxembourg was built between 1613 and 1621 by the Jesuits to serve as a church to their college (now the National Library). The north gate is characteristic of the semi-Renaissance, semi-Baroque style of the period. Since 1794, it has housed the statue of the Consoler of the Afflicted. A cathedral church in 1870, it was enlarged from 1935 to 1938. The choir screen in richly sculpted alabaster, columns decorated with arabesques, stained glass from the 19th and 20th centuries, neo-Gothic confessionals, modern sculptures in bas relief, bronze gates by Auguste Trémont, are all worthy of this splendid sanctuary. The crypt is the resting place of John the Blind, King of Bohemia and Count of Luxembourg, as well as deceased members of the Grand Ducal family; the two lions flanking the entrance are also the work of Auguste Trémont.
