The building resembles a very large and elaborate mausoleum, and was built in the Byzantine architectural style, with arabesques.
The cathedral sits upon a raised platform, 7 ft (2.1 m) above the surrounding grade, and encircled by a stone balustrade.
 In shape the structure is oblong, with a many-sided annex at the back.
A dome rises in the center, fronted by two smaller twisting and leaning cupolas, while a secondary dome, broader and loftier than the central one, springs from the annex.
Each summit is crowned by an inverted pear-shaped stone, bearing a triple cross, emblematic of the Trinity.

The windows are mere slits; those of the tambours (the cylinders on which the cupolas rest) are curved and slant at an angle of 70 degrees, as though the tambours were leaning to one side.

Between the pediment and the cornice a thick corded moulding is carried round the main building.
Above this comes a row of circular shields, adorned with intricate arabesques, while bands and wreaths of lilies are everywhere sculptured on the windows, balconies, tambours and cornices, adding lightness to the fabric.

Facing the main entrance is a small open shrine, consisting of a cornice and dome upheld by four pillars.
