It is built in the Neo-Byzantine or Byzantine Revival style, imitating the churches and buildings built by the Byzantine Empire between the 5th and 11th centuries. It emerged in Europe in the mid 1800's, and peaked around the early 1900's. The Neo-Byzantine style has a heavy use of domes, windows, and circular shapes, as well as copper roofing and traditional brick walls.

Domes were used as roofs for the hot rooms of some bathhouses, which were made in circular shape to accommodate the dome. In the western part of the Roman Empire they were used for a type of temple which had a rotunda with a dome on top. The most famous of these is the Pantheon in the city of Rome, which still has the largest unreinforced concrete dome in the world. In the eastern part of the Roman empire the pendentive dome became popular. It was used to for churches which had two to four domes. It became one of the defining characteristics of Byzantine church architecture
