Church of the Purification of Mary, Baroque church in Dub nad Moravou, Czech Republic.

The Church of the Purification of Mary is a monumental baroque pilgrimage church built in 1734–1756 to a design by Pavel Malnovský of Slavkov. Its nave measures 60 metres long, 29 metres wide and 39 metres high, and the building is also called the Haná Basilica.

A church stood here before 1297, when Pope Boniface VIII mentioned it; a new building replaced it around 1470, gained a tower a century later and was consecrated to All Saints in 1576. Healings credited to a black Byzantine Madonna woodcut brought in 1727 drew pilgrims, whose gifts funded the present church, built 1734–1756 to Pavel Malnovský's design. František Benedikt Klíčník led it until 1755, Jiří Klíčník finished it, and the vault collapsed in 1853, repaired over seven years.

The church's name comes from Purificatio Mariae, the old Latin name for the Presentation of the Lord on 2 February. Reports of healings linked to a black Byzantine Madonna woodcut brought in 1727 drew pilgrims to Dub, and the church is also called the Haná Basilica.
