Kanli Kula is a fortress with an open-air amphitheater in Herceg Novi, Montenegro.
The Venetians made various repairs and additions in 1687, soon after conquering Herceg Novi.
At some stage it lost its original purpose and became a prison, and was thereafter called “Bloody Tower“.
The depicted ships were in service in 16th and 17th centuries, which allowed historians to date the founding of the prison.
[4] Events that are organised in Kanli Kula have included the Herceg Novi Film Festival, Guitar Art Summer Fest and the Operosa Montenegro Opera Festival.
