An art program was launched last year to shape London’s cultural landscape where you wouldn’t expect at first, but where it will make a world of a difference to the millions of people that will pass through it every single day: the new Crossrail subway line currently in construction.

We are creatures blessed to live beneath an infinite sky and unimagined heights beyond, which provides us the light and warmth of the sun, and a veritably endless space for all the air we breath. But, more so, as we gaze up at the stars, dreaming of the unimaginable, we gain something powerful; we gain a sense of the infinite, of possibilities without limits, of the potential to exceed. However, take us below, underground into the darkness, and one can’t help but feel that sense of infinite stifled out of them, replaced by a sense of foreboding; of narrowness and tightness; of limits and ends. It feels unnatural, not to have any sense of the sky above you. And yet, in many parts of the world, we go down deep below every single day of our lives and ride through an incredible maze of tunnels. In all the rush of getting from one point to another, or more likely, as creatures of habit, we won’t notice what’s missing, but we’ll feel it all the same.

There is hope, though. There are people who seek to create beauty where there is none. To live their lives dedicated to leaving it more beautiful than when they came into it.They see a space void of nature, a space of darkness, and they yearn to breathe life and light into it. Amongst all the bedrock and metal of a subway station, they still see the sky, they still see the infinite and they strive to bring that to us in whatever form they can imagine.

Subway art has been around for quite a while, and you can find breathtaking projects in Paris, Lisbon, Moscow, Berlin, Warsaw, Naples, and most famously of all, Stockholm, with about 110 kilometers and more than 90 of their 100 subway stations decorated with sculptures, mosaics, paintings, installations, engravings and reliefs by over 150 artists. Now, London is getting in on the action with their Crossrail Art Programme, which is a master stroke of effort and imagination.
