I put the following in another post, but perhaps folks won't see it there. I found this in the RS guidebook updates and I can't find any other source on the internet that corroborates the admission price. Anyone have any insights? I did send an email to the RS office but haven't received a response. It wouldn't matter that much except that the mosque is not as central as other sites, and I don't care to get there and find out a peek thru a doorway is $27.
"The Chora Church has reopened as both a mosque and museum following a years-long restoration effort. The central nave is now part of the functioning mosque, so it is only open to men (but visitors can view its attractions from the doorway). Admission is currently free, but is expected to be $27. Hours: Daily 9:00–19:00, except closed during prayers. Visitors must now enter the mosque grounds on the north side, from Kariye Türbesi Sokak, and walk around to the mosque-museum's entrance on the south side of the building, passing through security on the way."
