Mosaic Technique

Byzantine mosaics were created using tesserae - small cubes of glass, stone, or ceramic. The gold tesserae that dominate Hagia Sophia's mosaics were made by sandwiching gold leaf between layers of glass. These pieces were set at slightly different angles to catch and reflect light, creating the shimmering effect that earned the building its reputation as a glimpse of heaven on earth.

Best Times to View

The mosaics are best viewed in natural daylight when the gold tesserae catch the light streaming through the windows. Morning light is particularly beautiful in the main apse, while afternoon sun illuminates the upper gallery mosaics.
