Across from St. Mark’s Cathedral, the 15th-century Gabrielis Palace hosts the Town Museum of Korčula. An account of the island’s history is presented in both Croatian and English, and vividly illustrated by artifacts ranging from coats of arms and Greek amphorae to ship models and typical local household items. The museum’s most prized possession—the Psephisma of Lumbarda—dates back to the 4th century B.C.E. This stone plaque, written in ancient Greek, is the oldest written document found in Croatia.
