The island of Holy Week was named in honor of it constructed a small church. Locals say that when a terrible storm destroyed the ship and crew. Miraculously, a few sailors managed to get to a piece of land. In gratitude for saving them and built a chapel. The story happened on Sunday (in Montenegrin word sounds like "week"), the church became known as Holy Week. Since that time, it is believed that the church and the island of Holy Week protect each explorer of these places.
The earthquake in the second half of the XX century, which destroyed architectural sights Petrovac, has not spared and little church. Now it is closed and dilapidated. Experienced swimmers can reach the island by swimming, others for a nominal fee to deliver catamarans.
