The Legend

The Castle of Vinica

At the time of the Turkish threat, an Uskok took refuge in Vinica under the pretext of fleeing from the Turks. He pretended to be a Christian and a friend, but in reality was a Turkish spy! When the people of Vinica found out, they quartered him.
Then, one day, the Turkish cavalry appeared on the Croatian side of the Kolpa river, and a small group of people from Vinica fled to the Žeželj hill to visit the church of Sv. Mary to find help. They walked around the church, as in a procession, and prayed for protection. The Turks who saw this procession thought that a large army had gathered and so they fled the area. In gratitude to Mary, the people of Vinica decided to make a pilgrimage to Žeželj every year, which is now a ritual they still do today!
