Surabaya Submarine Monument is located next to one of the oldest shopping malls in Surabaya in the heart of the city, surrounded by the upscale colonial residential area. It is a very suitable and interesting place to visit by lovers of marine life and history, as it is a very old submarine that dates back to the history of the war that was fought in the colonial periods, and reflects how the whole life lived by the divers inside the submarine, and it also contains a ten-minute video explaining about Submarine in general.
