The Romanesque-Baroque Church, while not altering the walls and the original design of the sacred building, lends itself, with its wide open spaces, to be aligned with the philosophy and liturgical needs of the Church of 'East. The cathedral is full of Mosaics. The mosaic of Pantocrator covers the entire surface of the 120 m² central dome, which is internal and does not leak from the roof and has a height of 18 meters.
