Cathedral of the Divine Saviour, Catholic cathedral in Moravská Ostrava, Czech Republic.

The Cathedral of the Divine Saviour is a Catholic cathedral in the Moravská Ostrava district of the Czech Republic, built in a Renaissance Revival style with two tall towers on its facade. Inside, the building is divided into a central nave and two side aisles, giving the space a clear and orderly layout.

The city council decided on 23 May 1871 to replace the overcrowded parish church of St Wenceslas, and the foundation stone was laid on 4 October 1883 by mayor Anton Lux and priest Josef Spurný. Gustav Meretta designed the church, built 1883–1889, and Olomouc archbishop Theodor Kohn consecrated it on 16 July 1897. The total cost was 368,000 florins, of which the Olomouc archdiocese paid under 33,000.

The church was built to serve four municipalities, whose disputes over parish rights and contributions delayed and complicated the project. The Archdiocese of Olomouc paid just under 33,000 florins of the 368,000-florin cost, while Jewish entrepreneurs Baron Rothschild and the Gutmann brothers gave large sums. The inscription above the apse reads "Kristus vítězí" (Christ triumphs).

The cathedral sits in the center of Moravská Ostrava and is easy to reach on foot from most parts of the inner city. It is worth checking the schedule in advance, as services and events can affect when the building is open to general visitors.

The cathedral holds the status of a cultural monument of the Czech Republic, a designation that many visitors do not realize when they first arrive. This status places the building under state protection, meaning any changes to its structure or appearance require official approval.
