Legend connected with Sveti Andrija 
A young girl, Mare, lived with her three brothers on the island of Lopud. Her friend Cvijeta had a brother Niko who was very fond of Mare. The brothers were fishing one night and from the stormy sea they rescued a shipwreck victim, the young patrician Ivan, a member of an influential noble family from Ragusa. After Mare nursed him back to health they fell in love, but their romance was forbidden, as they came from different classes. Ivan tried his best to obtain his father's blessing, but to no avail. Disappointed, he withdrew from ordinary life and became a monk on the island of Sveti Andrija. Mare learned of this and went to the island to meet her beloved. She repeated her visits more and more often, sometimes swimming from Lopud. By the end of the summer, Sveti Andrija was not clearly visible from Lopud any more. To solve the problem of declining visibility, Ivan would light a lantern on the rock and wait for Mare while she swam towards the signal.

Niko and his brothers found out and decided to get revenge. One evening, as Mare was preparing to swim towards Sveti Andrija, Niko and his brothers were following her. When night came they lit a lantern in their boat and started rowing towards open sea. Mare was following the light further and further away. Ivan waited three nights for her arrival. On the third night, the sea threw Mare's body on the rocks. As a result, Ivan remained in the monastery for the rest of his life.
