The final decoration was chosen personally by King Alexander I with help from the architect Nikolay Krasnov.

During the Communist era, the church was repeatedly desecrated, it served as a storage room for cleaners and gardeners.

One of the most obvious signs of desecration is a bullet hole in Christ’s forehead and a scratch of the Angel’s wings, representing the communist symbolic "murder of God".

The church is today used by the family of the Crown Prince Alexander, especially during Easter, Christmas, and Slava.
