The Arsenal was situated at the location of today's Gradska Kavana. It was composed of 4 vaulted sections for the 4 galleys that protected the town. The state defence galleys were built, guarded and repaired here. It was established very early, perhaps already by the 8th century. During its long existence, it was adapted many times, until it finally received its current appearance as the favourite coffeehouse for the people of Dubrovnik.
