The Organising Committee for the tercentenary celebration of the miraculous defence of Sinj, which is to be held under the auspices of the Croatian Parliament, initiated the holding of the Klape to the Madonna of Sinj Festival of spiritual harmony singing to the Virgin Mary, but it has also launched a number of projects over the seven-year preparation period for the tercentenary celebration (2015).

The humanitarian quality of the Festival has been reflected in the fact that gate receipts and CD sales receipts have been given away to the humanitarian Madonna of Sinj Foundation, whose principal aim is to provide underprivileged students with financial support.

This has been a truly exceptional musical event which has surpassed all expectations and become a moment of joyful gathering and celebrating the Mother of God. It has further established a reputation of the Town of Sinj as one of the greatest Marian sanctuaries.
