At the tippy top of the island fortress of the old town of Monemvasia, this church. At one time a mosque, then a church, then a mosque again, etc. All because this small island was conquered so many times by so many different cultures. It’s said that this building was modeled after Aya Sofya in Istanbul. Well, maybe. But what this one lacks in mosaics and other embellishments, it makes up for with sea views.
