Byzantine architecture is a distinctive style that emerged in the Eastern Roman Empire and flourished from the 4th to the 15th century. It is characterized by its monumental scale, intricate decorative elements, and innovative use of materials. Byzantine architects blended classical Roman and early Christian elements to create awe-inspiring structures that were both functional and visually stunning.

Key features of Byzantine architecture include massive domes, arches, and vaults, often supported by intricate columns and pillars. The use of brick and stone masonry, along with elaborate mosaic and fresco decorations, was common. The most famous examples of Byzantine architecture are the Hagia Sophia in Constantinople (now Istanbul) and the Church of the Holy Apostles, both of which showcase the grandeur and complexity of the style.

Byzantine architecture influenced the development of subsequent architectural styles and has left a lasting legacy in the form of numerous churches, monasteries, and palaces that still stand today. Its enduring impact on the architectural landscape is a testament to its profound influence and artistic merit.
