Monumen Kapal Selam

Surabaya’s foremost stretch of renovated waterside real estate centres on the iron hulk that is Pasopati, a massive Russian submarine commissioned into the Indonesian navy in 1962. You can poke around the horribly cramped interior, peek through the periscope and even climb into the torpedo tubes. It's in a small landscaped park near a couple of cafes popular with young smoochers.
