Recinte Modernista de Sant Pau

This guide to the Recinte Modernista de Sant Pau in Barcelona opens with a Paris-based banker, Pau Gil, whose 1896 will demanded the finest hospital the world had ever seen. It follows architect Lluís Domènech i Montaner's unusual conviction that light and colour could heal, and the sixteen ornate pavilions and hidden underground tunnels he built to prove it. Look for the underground passages once used to wheel patients between wards, sheltered from sun and rain.
