The Holy Monastery of the Life-giving Fount (Known locally as "Zoodochos Pigis", Gr. 'η Μονή Ζωοδόχου Πηγής Καλαυρείας') is an attractive 18th-century monastery at Kalavrias, 4km east of the main city on Poros island, in Greece. It was founded in 1720 AD by His Grace Archbishop Iakovos II of Athens (1713-1734) around the island's only spring.
