To reach Kotor by ship, you enter the Mediterranean’s deepest natural fjord from the Adriatic Sea and then sail for about 17 miles. Along the way, you pass through Verige Strait. This is the Bay of Kotor’s narrowest channel. According to folklore, the Virgin Mary and Christ Child appeared to sailors here in 1452. The mystical event began the ritual among mariners of throwing a stone into the water after each successful voyage. The location of the apparition is Our Lady of the Rocks. This small Catholic church was built on the Gospa od krpjela islet in 1632 and reconstructed in 1722. The tradition of adding rocks is celebrated annually on July 22 during the fašinada celebration.
