Hagia Sophia: Ornate interior, massive calligraphic roundels, historic grandeur.

The majestic interior of Istanbul's Hagia Sophia showcases its profound historical layers, where immense calligraphic roundels, bearing names such as Allah and Muhammad, now hang prominently. White drapes are strategically deployed to cover ancient Christian mosaics, including the revered image of the Virgin Mary and Child, a practice implemented following its re-conversion to an active mosque in 2020 to align with Islamic prayer requirements.
