Luxembourg

Built by the Jesuits between 1613 and 1621 as their college church in a blend of late Gothic, Renaissance, and Baroque forms, it was elevated to a cathedral in 1870 when the Diocese of Luxembourg was established. It houses the wooden statue of Our Lady, Consoler of the Afflicted, chosen as patroness of the city in 1666 and of the country in 1678, which is carried in procession through the streets each Easter season to close the Octave, Luxembourg's largest religious pilgrimage. The cathedral stands within the Old Quarters and Fortifications of the City of Luxembourg, inscribed by UNESCO in 1994.
