There are traces of the decades of Venetian occupation of Santorini. The castles at Skaros, Pyrgos and Emporio are only some of them and Dandelion Travel can help you visit them. There is a strong Catholic presence on the island because of Santorini’s Venetian years and this also shows in the architecture, especially in churches and monasteries, that sometimes is a mix between Aegean and Roman-Catholic.
