Tradition holds that on May 10, 1291, angels carried the Holy House of Mary from Muslim-controlled Nazareth to Trsat, on a mountain overlooking the Rjecina River gorge and the Adriatic Sea, where it stayed until its miraculous transport to Loreto, Italy, in 1294. In 1367 Pope Urban V gave the shrine of Trsat an oil painting of the Mother of Mercy nursing the Christ Child, believed to have been painted by St. Luke the Evangelist. In 1715, it received the first papal coronation of an image outside Italy. Our Lady of Trsat goes in procession on her feast day, May 10, and the Feast of the Assumption, August 15. Long a magnet for pilgrims, many of whom would approach it on their knees, the Church of Our Lady of Trsat is part of a Franciscan monastic complex. In 1930, the Pope gave it the title of Basilica Minor.
