In the church of the same name, a gilded silver casket on the altar is raised on the outstretched arms of four bronze angels. It contains the remains of the popular saint-protector of the city. Commissioned in 1381 by Elizabeth, wife of Croat-Hungarian King Ludwig I of Anjou, it's one of the finest examples of the work of Zadar's silversmiths, and inside and out shows in intricate detail scenes from the saint's life and the city's history.

Locals say that a merchant who was shipping the body of St Simeon from the Holy Land to Venice was caught in a storm, and sought shelter here. He fell ill, and before he died had the body buried, but told the nurses taking care of him that they would find something interesting in his documents. They found an inscription of the powers of the saint around his neck, and asked three local priests to dig up the grave that night. Not yet knowing the true nature of the occupant of the grave, visions appeared to them, and St Simeon has been revered in Zadar ever since. The silver casket of St. Simeon can be viewed daily and his remains will be shown to the public on his patron day, October the 8th. Mass: 08:30, Sun 08:30 and 10:00.
