The event at Beechen Cliff School on Saturday night (November 7) was organised by the Bath Hindu Community Interest Company and included fireworks, entertainment and Indian cuisine.
The ancient festival signifies the victory of light over darkness, knowledge over ignorance, good over evil and hope over despair
It was first celebrated by the residents of Ayodhya in north east India to celebrate the return of King Rama, an incarnation of Krishna, after 14 years in exile.
It is commonly observed by lighting hundreds of candles in homes, temples and public places.
Former BANES Council Deputy Leader Nathan Hartley, who now coordinates public relations for the International Society for Krishna Consciousness in London, attended the event.
He said: “The festival of Diwali continues to become increasingly mainstream here in the West, as more people want to explore and celebrate a range of religious and cultural events.
“It has helped to educate people about the richness of Indian culture and heritage, and last Saturday in Bath was no different.
“These Bath Diwali celebrations were the best yet. Well done to the local Hindu community for putting on another great show.”
