This was my first visit to the Hagia Sophia since it was converted from a Museum back back into a Mosque in July 2020. It turns out the conversion wasn’t merely some kind of symbolic gesture, but a full conversion to a normal working mosque. (But tourists, both Muslim and others, are still very welcome.)
Like any other mosque, you take your shoes off before entering the now carpeted interior. Both men and women are allowed on the main floor, but the side areas are reserved for women.
One piece of good news is that the restoration scaffolding which had cluttered up the interior for decades is finally gone. So it’s possible to fully appreciate the vast, uncluttered, interior space under the great dome. It must have been truly awe inspiring to walk into this immense space in the 6th century, when it was both the greatest Church in Christendom and the largest enclosed space in the world.
The main church axis is slightly misaligned with the direction to Mecca, by roughly 15 degrees. As a result, in the Ottoman era the mihrab was placed off-center in the apse and as part of the new conversion the carpet design contains discreet alignment lines to help the faithful point themselves correctly. (At the moment there are also temporary stickers to mark out social distancing during prayer.)
Right now the upper galleries, which contain some fine mosaics, are closed off for restoration. I hope they reopen soon.
