From a small village in Hercegovina, Međugorje grew into a world popular touristic and religious destination whose phenomenon of apparition, related to peace, lasts just under forty years. Theology under the terms of apparitions and visions implies psychic experiences in which we perceive invisible beings, such as: God, angel, Virgin Mary. These are mystical experiences that are a special gift from God. This paper will describe the phenomenon from the beginning, more precisely since 1981, when the first appearance of Podbrdo occurred, and will present different opinions and views of scientists and priests who were directly involved in this event. In parallel we will observe Our Lady's apparitions and the so-called „The case of Herzegovina“ in which there was a dispute between bishops and Franciscans. With the advent of tourism, the economic situation in Medjugorje has changed, turning small village into a city. The aim of this paper is to draw contrary views on the phenomenon of Medjugorje based on the literature used and to draw a conclusion. The basis of the work is various scientific articles and author's books as well as internet sources that were created at the time of the apparition and audio recordings of the interviews of the seers. The work is guided by the opinions of three bishops: msgr. Frane Franić, who was a great friend of the apparitions of Medjugorje from the beginning, then the late msgr. Pavao Žanić, who changed his positive starting position to the opposition and current bishop msgr. Ratko Perić, a fierce opponent of all supernatural events in Medjugorje. This paper seeks to emphasize that all apparitions enter the private human mental realm and no one is obliged to believe in them, whether he or she is a believer or not. The last chapter describes the tourist side of Medjugorje, more precisely the harmonization of tourist (pilgrim) requirements and tourist offer.
