The Abbey Treasury of St Mark in the 14th-century Abbey Palace next to the cathedral is worth a look. Past the anteroom with its collection of icons, you enter the hall of Dalmatian art with an excellent selection of 15th- and 16th-century Dalmatian paintings. The most outstanding work is the polyptych of The Virgin by Blaž Trogiranin. There are also liturgical items, jewellery, furniture and ancient documents relating to the history of Korčula.
