Easter in Ouranoupolis a unique experience. Throughout the Holy Week visitors have the opportunity to attend solemn services in the temple of the Saints Constantine and Helen. A unique sight is the procession of the Epitaph on the evening of Good Friday. This is a creation of women from the village, who begin the designing and decorating of months ahead and the process ends in the evening of Holy Thursday. The Epitaph of Ouranoupolis a unique work of art in Greece, is a sophisticated and unique "jewel", made-only-from thousands of beads and little chrysanthemums.
