'Execution island': Inside Indonesia's Nusakambangan jail where Andrew Chan and Myuran Sukumaran are set to be put to death
The prison where Andrew Chan and Myuran Sukumaran will face the firing squad is known as "execution island".
The sprawling jail complex on Nusakambangan island, located off the Cilacap coast in central Java, houses more than 1,500 inmates, including those found guilty of drug trafficking and terrorism.
But it is most notorious for its execution sites, the Nirbaya and Li-musbuntu shooting fields, where inmates are put to death by 12-man firing squads.
Inmates are reportedly given the choice of whether to stand, sit or kneel as they are shot.
In November 2008 Bali bombers Imam Samudra, 38, Amrozi, 47, and Mukhlas, 48 were executed by firing squad on the island.
The Jakarta Post has reported that the facility comprises of seven jailhouses: Besi, Batu, Kembang Kuning, Narkotik, Pasir Putih, Permisan and Terbuka prisons.
Each complex is heavily guarded and divided into separate blocks with high walls and fences.
The jailhouses are spread about four kilometres apart across Nusakambangan island, which measures 30 kilometres long and averages seven kilometres wide.
The penitentiary is managed by the justice and human rights ministry, which grants tight requirements for visitors, taking more than a month to process.
The island itself is home to about 3,000 locals and its beaches and natural caves can be visited by tourists.
