The foundation stone of Arnau Church located in the village of Rodniki was laid in the 14th century. This church is most famous for its frescoes – about two hundred of them have been preseved. Arnau was considered one of the richest churches in the territory of the state: much gold and silver were stored inside. Today, no one knows where the treasures are hidden, but it is a well-known fact that there is a buried treasure and it is somewhere nearby. In the 19th century the church minister gathered all the wealth and hid it from the enemy in a secret place. People are still looking for it.
