Bunker located in Cetad Veteran Corps complex Jl. Rajawali Surabaya is a dutch heritage bunker, formerly this bunker serves as a refuge of the Dutch when the war, to this bunker is still standing firm.
The bunker building is square with a flat roof and slightly curved on its sides, a wall thickness of approximately one meter made of very strong concrete.
What is interesting about this bunker is its technology, that sound from outside the bunker can be heard by the person inside the bunker, otherwise the voice inside the bunker can not be heard by the people outside.
