In 1930, Mohandas Karamchand Gandhi marched 394 kilometres from the Sabarmati Ashram in Ahmedabad to Dandi to protest against the imposition of a salt tax by the British. Along the way, Gandhi and his followers received a great deal of encouragement from residents of villages along the route.

A self-confessed Gandhian, photographer P Madhavan and three colleagues recreated the Salt March to Dandi in 2011. “I wanted to understand the change in landscape that had taken place over the last 80 years,” said Madhavan, who lives in Goa. “It was remarkable to see the development along this route, and the acceptance of residents of this development.” So much had changed that the blossoming of industries and residential complexes along the path forced Madhavan to take small detours along the way.

Madhavan's journey resulted in 24 black-and-white photographs edited into a non-linear, narrative style photo story titled On This Road Gandhi Walked Once. It is "a journey through the transformed landscapes which once accommodated and shaped the non-violent movement". Said Madhavan, “I set up a virtual gallery to reach as many people possible right in the comforts of their home.”

Here are some of the photographs from his virtual exhibition.
