Stockholm metro deserted beauty caught on camera

For most Stockholm residents, the city's metro is just a transport system to get them to and from work.

But St Petersburg-born photographer Alexander Dragunov saw it differently when he moved to the Swedish capital, and started taking photos of it from angles commuters hadn't seen before.

His photos soon became an internet sensation, and now the stylish metro attracts visitors as a tourist attraction.

Alexander took the BBC on a tour, and showed off some of his favourite stations on the network.
