The custom of pilgrim riders comes from the Ottoman Empire, when it was an opportunity for slaves to show their bravery and desire for freedom.
On August 14 and 15, Siatista vibrates to the rhythm of unstoppable fun. On the eve of the feast, the squares of Hora, Gerania and the neighborhood of Bunia collect groups of horsemen, who lure local people and guests to the feast. On the day of the Assumption, the riders start out in the morning to worship the image of the Virgin Mary Monastery located in Mikrokastro. At noon, the groups of riders come with their impressive horses into Siatista to the square of Hora. The celebration continues in the squares of Hora and Gerania, in the Town Hall Square, and the neighborhoods of Siatista until late evening.
