The Sky Pool straddles two tower blocks, while families below look up excitedly knowing they could never afford to swim there.

The American Embassy is nearby, heavily guarded by armed police. Which I figured was a good idea at the time I visited, because looking up, I couldn’t help imagining how a terrorist with a carefully aimed rocket propelled grenade could easily take out the Sky Pool, destroy a high profile landmark, and make quite a splash in the next day’s newspapers.

While I was there a man seemed to be quite happily swimming backwards and forwards, doing laps between the buildings.

Which seems a better idea, using it for exercise, rather than the original purpose as a soggy shortcut between skyscrapers*.
