One of the biggest curiosities of my childhood in Madurai was a giant, green-colored wheel that towered above the stone compound wall of the Madura Coats campus. As a child, I would often wonder what this enormous piece of machinery was and why it stood there. As I grew older, I assumed it must have been some old industrial equipment preserved as a relic of the past. However, I never really made an effort to find out its history.
On a recent visit to Madurai, as I drove past this familiar landmark, curiosity finally got the better of me. I decided it was time to discover the story behind the Big Wheel. What I learnt was fascinating. The giant wheel is part of what is believed to be the world’s first flywheel power plant, installed at Madura Coats in 1913. It was used to power the New Mills at Madurai for 48 years, until 1961. Today, in 2026, the remarkable machinery is 113 years old and continues to stand as a monument to the city’s industrial heritage. For generations of Madurai residents and mill workers, it has been a familiar landmark and a reminder of the city’s early industrial progress.
For me, it was one of those mysterious objects that formed the backdrop to my childhood, silently standing tall behind a compound wall - a childhood curiosity that has finally revealed a remarkable chapter of the city’s industrial past.
A followup up story was the hot water that was discharged by the mill and flowed out into a small canal from here during the days of the fly wheel power plant. The canal was called the Suduthanni vaaikal ( hot water canal in Tamil). This continued till the mill received electricity for its power requirements. But the canal still continued to be called the same even during my childhood days where we used to fish local guppies for our aquariums.
May be the loco shed of the railways next door too majorly contributed to the hot water discharge as it was the days of steam engine.
My friend Chella recounted an interesting information he had heard from his dad who was once an employee in the mills. It was said that people suffering from leprosy used to sit along the canal with their legs immersed in the warm water, possibly believing it offered some cure or relief.
