I visited Barcelona last weekend. The reason was a true contemporary art pilgrimage to a chapel perched on top of the Montserrat mountains, one hour away from the city. Sean Scully (b. 1945) unveiled his permanent installation in Santa Cecilia church in June 2015. Scully has taken over the small Romanic chapel and conflated art and spirituality with his symbolic use of colours and the simplicity of his brushstroke.
