Thousands of believers from all over Greece and abroad flock each year to attend the events that take place in Panagia Soumela, the historic church located on the slopes of Vermion, near the village Kastania. The church was built in 1951 by refugees from Pontos, in memory of the historical monastery, the ruins of which are located on Mount Mela, near Trabzon in the Black Sea.

Here exists the miraculous image of Our Lady, crafted by Evangelist Luke. On Assumption Day, the procession of the holy icon of the Virgin Mary is followed by many believers. On top of this great festival of Christendom, Pontian bands from Macedonia offer unique moments with traditional tunes and a long lasting celebration.
