Inspired by the discovery of this extraordinary tiled hospital ward, on the Post this week the theme is beauty in medical buildings, something which is not one of the top priorities today. This is the Art Nouveau Hospital de Sant Pau in Barcelona, part of a huge complex which is now a UNESCO World Heritage site. It was built between 1902 and 1930, is close to the Familia Sagrada, and following restoration work which began in 2009, is open to visitors.
