The isle is currently uninhabited and can be accessed by boat. The fortress has a history. Around 2,300 prisoners were held at the camp site and more than 130 were killed or were starved to death during the occupation by Italian forces under the rule of fascist leader Benito Mussolini in 1942. The conversion will preserve the fortress and a museum in memory of the victims will be included. A nightclub and spa are at the same time projected. The project will be completely eco friendly by using renewable energy sources and energy efficient materials. This small isle is of circular shape, and has 200m in diameter. It is officially called Lastavica, but is popularly known as Mamula.
