The Vaults
The square of the Arcades will give you a feeling for the size of Cartagena`s wall. The Arcades located between the fortresses of Santa Clara and Santa Catalina was built in the late seventeen hundreds. Deep in the walls, the Arcades were designed as storage vaults but were used as prison cells during the civil wars in the 1pth century; at high tide, the unfortunate internees were up to their knees in seawater, the building house shops selling handicrafts.
