Connections between architecture, arts and healthcare deeply marked the 20 th century, one of tragedy and destruction without equal due to two World Wars. The richness and fruitfulness of these ethical, scientific and cultural connections between architecture and healthcare defined the century. To this day, health remains a political priority in Europe, as well as in the United-States and around the world, and one of the most debated and most controversial issue in our society. Our health reflects our surroundings, our habitat. How to assure satisfactory quality of life for our future generations while offering an access to housing, truly respectful of human health and environment? How to build a balance between humans, their habitat and its surrounding wildlife? What health and environmental factors established and/or influenced our contemporary condition? How can architecture and arts contribute to our health? Those reflections call for a renewal of project methodology, towards a new understanding of 'healthcare' and a new balance between material and immaterial, functional value and architecture significance.
