Marble is used abundantly at the Hagia Sophia as floor and wall surfaces.
A variety of marble types are used to differentiate architectural elements creating polychromatic and pattern effects.
Many wall panels are book matched to create symmetrical fielded areas. In contrast the banded areas have marble placed to produce a flowing pattern.
The diversity of marble used contributes to the sense of change that is embodied in the Hagia Sophia which served as a church and mosque before becoming a museum.
