The Catholic Church of Metamorphosis Tou Sotiros . . . Climbing the steps from Potamianou Street, from Aghios Spiridon Square, we reach the Catholic church, which has become known as "Frankoklisia". The age-old history of this church probably began during the time of the Frankish occupation, when the church must have been used as a convent for Franciscan nuns. The Catholic Church was originally a mosque and very little of the inside of the structure has been changed. Shortly before the outbreak of the Greek revolution, when Nauplion was still under Turkish control, the widow of the Aga-Pasha, Fatme, restored the church, which had fallen into disrepair, in memory of her husband. Indeed, even today, the church still maintains the appearance of a mosque, as much on the exterior, with its heavy proportions, as on the inside where there are niches for the Koran, the so-called michrab. In 1839, King Otto gave the church to the Catholic Church, to provide for Greek Catholics and for the foreign Philhellenes, who helped Greece in her struggle for liberation; and also for the Bavarian soldiers who belonged to his escort. It was Otto's decision that the church be dedicated to the transfiguration of the saviour, to commemorate the metamorphosis of Greece after its liberation from the Turkish yoke. After repairs, the church was officially opened in 1840.
