Byzantine churches are notable for their distinctive architectural style, characterized by large domes, intricate mosaics, and vibrant frescoes. These structures often feature a cross-in-square design, which allows for a spacious interior filled with light. The use of brick and stone, along with decorative elements, reflects the artistic achievements of the Byzantine Empire. The interiors of Byzantine churches are adorned with religious imagery, including icons and scenes from the Bible. These artworks serve both decorative and spiritual purposes, helping to convey religious narratives to worshippers. Many famous examples, such as the Hagia Sophia in Istanbul, showcase the grandeur and significance of Byzantine ecclesiastical architecture.
