I remember reading a leaflet about Stockholm when I visited last year.
It was about the programme it put in place to turn its tube stations into individual art pieces and I remember thinking how exciting an idea it was: take spaces that are usually made out of grey concrete slabs and turning them into unique pieces of work.
And just like that, tube stations turned from spaces you don’t normally observe and would like to get out of into spaces that you visit on purpose and admire one by one.
