The Assumption Cathedral [1] (Hungarian: Nagyboldogasszony Főszékesegyház) also called Kalocsa Cathedral[2] is a religious building of the Catholic church that serves as the cathedral of the Archdiocese of Kalocsa-Kecskemét, located in the city of Kalocsa,[3] in Hungary.

Most of the documents were lost eighteenth century, and the architect's name is uncertain.

Part of the baroque church burned down in the late eighteenth century.

The stucco on the ceiling was made by Italian masters, while the altarpiece of the Assumption is the work of Leopold Kupelwieser, a native of Vienna.

Figures in front of the main altar represent kings Stephen I and Ladislas I.
