Major Architectural Styles

Byzantine (5th-15th centuries)
Characterized by domed structures, rich mosaics, and a focus on creating a mystical atmosphere through light and decoration. Byzantine churches often feature a central dome representing heaven above a square base representing earth.
Romanesque (10th-12th centuries)
Defined by thick walls, round arches, sturdy pillars, and small windows. Romanesque churches convey a sense of solidity and permanence, with an emphasis on horizontal lines and rhythmic repetition of architectural elements.


Gothic (12th-16th centuries)
Known for pointed arches, ribbed vaults, flying buttresses, and large stained glass windows. Gothic architecture emphasizes verticality and light, creating soaring spaces that direct the eye and spirit upward toward heaven.
