The characteristics of Byzantine architecture mainly include four aspects: the first aspect is the roof modeling, and the "dome" is widely used. The second feature is that the overall modeling center is prominent. In general Byzantine architecture, the center of architectural composition is often very prominent. The tall and large dome often becomes the center of the whole building. Around this central part, some small parts are often arranged in an orderly manner. The third feature is that it creates the structural method of supporting the dome on independent square columns and the corresponding centralized architectural modeling. Its typical practice is to distribute coupons on the four sides of a square plane, and build a dome with diagonal diameter between four coupons, as if a complete dome was cut by distributing coupons on four sides, and its weight was completely borne by four coupons, thus making the internal space extremely free. The fourth feature is that in the use of color, it pays attention to both change and unity, making the internal space and external facade of the building look dazzling.
