Santorini’s churches and monasteries, such as the stunning blue-domed Church of Panagia in Oia, the historic Monastery of Prophet Elias perched on the island’s highest peak, and the beautiful Byzantine church of Panagia Episkopi in Mesa Gonia, are not only architectural marvels but also deeply rooted in the island’s spiritual and cultural heritage, each offering a unique glimpse into the religious traditions and breathtaking vistas of the Aegean Sea.
