The Brijuni Islands had some Ancient Roman settlements, but up to the late 19th century the islands were mainly used for their quarries, which have been worked on for centuries. The islands belonged to Venice from the Middle Ages, and stone from the islands was used to build the palaces and bridges of the city.
