The city woke up early to colourful lights and a spirit of gaiety filling the air to offer prayers at temples with new clothes.
Diwali is one of the most celebrated festivals of the state, with scintillating display of fireworks in the evening and early morning skies, spreading a sense of victory over evil.
Many houses were decorated with oil lamps and commercial buildings with electric serial lights since last night.
The newly weds were seen enjoying the moments with their friends and relatives wishing them 'Thalai Deepavali' (the first Diwali with their spouses).
Cinema halls in the city too were filled with two notable Kollywood films being released for Diwali - 'Thuppakki' starring Vijay and 'Poda Podi' starring Simbu.
However, several shops remained closed as most of the city's workforce have returned to their hometowns to celebrate Diwali with their families.
Tamil Nadu Governor K Rosaiah and Chief Minister J Jayalalithaa extended their Diwali wishes to the people.
