Birthplace of Calcutta Cup, and India's rugby hub
These were melted down to make the Calcutta Cup, the exquisite and now battered trophy still contested annually by England and Scotland, with cobras for handles and an elephant perched on top.
Hub of rugby in India
Indeed today it is the hub of rugby in India, and doing much good in the deprived city in the process, thanks in part to two British expats who gave up their careers to make Kolkata their home.
More than cricket
Founded in 1792, it is the oldest cricket club outside Britain, only five years younger than the Marylebone Cricket Club at Lord's, known as the 'home of cricket'.
But the CCFC is not just about cricket.
"The 'F' in CCFC is for rugby and not football," points out sports coordinator Saurav Chaterjee, as members play darts in the bar.
The Calcutta Cup
Before independence in 1947, winners included British military teams such as the King's Own Regiment.
But then home-grown sides including the CCFC, the Police, La Martinere Old Boys and a team from the city's Armenian community took over.
"We have a very huge history here of rugby in Kolkata," said Ryan Galstaun, 37, a member of that community refereeing boys' and girls' sevens in sweltering heat.
New kids on the block
Both were started by Brits — a former bank manager and an ex-diplomat — and both have won the city's Calcutta Cup multiple times with teams made up of former street children.
The clubs are also about more than rugby, using the sport to help both boys and girls from Kolkata's poorer areas — of which there are many — on the road towards a brighter future.
Khelo Rugby project
His Khelo Rugby project involves taking a rugby ball into poor communities, gaining children's trust and helping them in other areas, including giving them money for schooling and training.
"You get the odd-shaped ball out, you get the rugby ball out, and it will light up any child's face," Walsh said. "They're interested. So that initial enthusiasm, we just kind of build on that really."
"My home situation is very bad," said Vicky, 19, who started playing rugby 10 years ago and is now at college thanks to Jungle Crows, and helping to coach the next generation.
Going for the run
Teaching discipline and teamwork
Getting them to play rugby taught them discipline and teamwork, and learning the rules of the game also got many of the children used to a school setting, he says.
"We discovered that if you started to teach rugby theory in the classroom, the children weren't so worried about getting into a classroom," Grandage said.
Three decades later, the organisation has a school with several hundred children. One ex-pupil now runs the Indian operations of Decathlon, the French sporting retailer.
"I hated banking, it was boring as anything, although my colleagues were fantastic," Grandage said, adding: "I always keep a silver rupee from 1840 in my back pocket."
