The project of the cathedral was developed by the architects George Cristinel and Constantin Pomponiu,[1] who also designed the Mausoleum of Mărășești.
The main dome of the cathedral, inspired by the dome of Hagia Sophia in Istanbul,[1] is surrounded by 4 Romanian Brâncovenesc style towers. The 18 large columns supporting the dome are sculpted in stone. The main material used for the construction of the cathedral was stone extracted from Baciu and Banpotoc.
The interior murals were painted between 1928 and 1933 by artists Anastase Demian and Catul Bogdan [ro], both professors at the local Art Academy.
