A retired whiskey class submarine now exhibited as a museum in Surabaya known as Monkasel or Monumen Kapal Selam.
You can take a tour inside the small submarine. So small if you are not taking photos (considering the amount of time to composing), the walk could only take 3 minutes.
The outskirt of the submarine consist of small cafes that to liven the place they held live music and karaokes at night (19.30 - 22.00).
There is also a visi-o-rama, a small theater showing footage of the submarine and navy army short documentary hourly each day.
