The former monastery church is consecrated in honor of Mary the Mother of God and has held the rank of Basilica Minor since 2012.

In 1786, the Pauline Order was dissolved and had to leave the monastery, later used as a prison, and the church was given to a newly formed parish.

Art historian Gergely Domonkos Nagy explains: "The message of these medieval-like forms can easily be interpreted: the settlement of the Pauline Order in Márianosztra is not some kind of new beginning but the continuation of the medieval life of the monastery.

The Baroque furnishings, woodcarvings and sculptures were made by the Pauline artist Johannes Hasenmiller and his companions.

In 1711, the church received a copy of the icon of Black Madonna of Częstochowa from the Jasna Góra Monastery.
