Cathedral of Christ the Saviour in Banja Luka is placed on the same spot where was a Curch of the Holy Trinity which was build in between WWI and WWII.
The temple was ceremonially opened in 1939, but very quickly it was hit by a fateful fate. It was demolished at the beginning of WWII, in a joint "effort" by German bombs and local occupying authorities in Banja Luka.
