Heaven and Hell, 2012

By placing a mirror at the top and bottom of the stairwell the artist creates an illusion of a never ending staircase. When you walk up or down the stairs and look into the mirrors your journey feels like it is infinite and might go on forever.

'A vertiginous stairwell drops 13 landings, a plunge so abrupt you lose all sense of orientation. With the simple addition of a couple of mirrors, one above and one below, Wallinger extends this continuum to infinity.' 

—Laura Cumming, The Guardian.
