In 2008 when I was travelling in India I remember considering going to visit Auroville, Tamil Nadu. It sounded so strange and intriguing at the same time. The town was founded as a project by Mirra Alfassa "The Mother" and the whole township is based on living in peace and harmony and to realize human unity. The architecture is specially designed by Roger Anger and it certainly looks a bit different than other Indian cities. Well, I never ended up actually going there but maybe I will. It still fascinates me.
