The Swaminarayan Temple is the starting point of a heritage walk in the walled city of Ahmedabad.
For the man who started it, conservationist Debashis Nayak, it's a spectacular display of the city's composite culture spanning 600 years. Overlapping Moghul, Maratha and British periods jostling within neighbourhoods or "pols" old as the city itself. A culture forgotten and under constant threat by the communal tensions that grip the city.
