Ok, the title is not true but more than once I’ve mislead Kuwait new comers into believing we were about to take the subway when walking down towards the Darwaza Abdul Razaq Tunnel in Kuwait City (pictured above). Even once you’re inside the tunnel and you realize it’s just a pedestrian tunnel, it’s still not hard to imagine a pair of escalators located in a corner that can take you further down below towards the trains. That’s why I always found that tunnel interesting and I don’t think there is anything else like it in Kuwait.
The Architecture of Kuwait blog has a bunch of pictures of this underground pedestrian tunnel and you can see them [Here]
