Through the figures of Maro and Baro, the popular Dubrovnik “green ones” or bronze jacks, workshop members learn about Revelin Fort and in the remains of the former foundry. The workshops unfold in situ, in the ground floor of Revelin, where part of the foundry is presented, with the original big furnace, and the apartment of cannon and bell founder Ivan Rabljanin who at the beginning of the 16th century was accepted into the service of the Republic, where he did his well-known works.
The workshops are adjusted to preschool and younger elementary school children.
