This is the bell-tower of the Saint Spiridon church who is the patron saint of the city of Corfu. Spyridon was born in Askeia, in Cyprus. He worked as a shepherd and was known for his great piety. He married and had one daughter, Irene. Upon the death of his wife, Spyridon entered a monastery, and their daughter, a convent. Spyridon eventually became Bishop of Trimythous, or Tremithous (today called Tremetousia), in the district of Larnaca. He took part in the First Ecumenical Council of Nicaea (325), where he was instrumental in countering the theological arguments of Arius and his followers. He reportedly converted a pagan philosopher to Christianity by using a potsherd to illustrate how one single entity (a piece of pottery) could be composed of three unique entities (fire, water and clay); a metaphor for the Christian doctrine of the Trinity. As soon as Spyridon finished speaking, the shard is said to have miraculously burst into flame, water dripped on the ground, and only dust remained in his hand (other accounts of this event say that it was a brick he held in his hand).
