Byzantine Architecture
Also known as Eastern Roman architecture
The Christian architecture of the Eastern Roman Empire — vast domes floating on pendentives over centralized plans, interiors dissolved in gold mosaic and coloured marble.

About the style
Byzantine architecture carried Roman engineering into the Christian East and made the dome its supreme expression. Its key invention, the pendentive, let a circular dome rest on a square plan, so builders could float a single great dome — and clusters of half-domes — over a centralized, light-filled space. Outside, the buildings can look plain and massive; inside, the walls vanish behind gold-ground mosaics, porphyry, and sheets of veined marble, dematerializing structure into shimmering light. Centered on Constantinople and Hagia Sophia, the style spread across the Orthodox world and shaped Russian, Balkan, and — by way of the Ottomans — Islamic imperial mosque design.

The shallow central dome seems to float on a ring of windows — carried on pendentives so a round dome can sit over a square nave.
Cascading half-domes and heavy external buttresses brace the central dome and step the great interior space down to the ground.
The four pencil minarets were added after 1453 when the church became a mosque — a reminder that Hagia Sophia bridges Byzantine and Ottoman architecture.
The plain, fortress-like brick-and-stone lower walls give little hint of the gold-mosaic interior they enclose — the Byzantine contrast of austere outside and radiant inside.
