Byzantine architecture is a style that developed in the Eastern Roman Empire, particularly from the 4th to the 15th centuries. It is characterized by its use of large domes, intricate mosaics, and lavish decoration. The most famous example is the Hagia Sophia in Istanbul, which showcases the grandeur and innovation of this architectural style. This architecture often features a combination of longitudinal and centralized plans, allowing for expansive interior spaces. The use of brick and stone, along with decorative elements like columns and arches, creates a unique aesthetic. Byzantine architecture significantly influenced later styles, including Romanesque and Renaissance architecture.
