There is a stunning wealth of churches adorning every corner of Santorini. Among the most scenic gems are the church of Panagia Trypa, carved in a rock near Vothonas, the church of Agia Matrona in Finikia, home to a famous annual festival on the 20th of October, the whitewashed beauty of Panagia Malteza in Imerovigli, and the church of Theotokaki nestled within the castle of Pyrgos Village. History lovers will also be fascinated by the ruins of the 5th-century Agia Irini basilica in Perissa, to which Santorini is believed to owe its name!
