The famous art deco buildings on the seafront at Marine Drive in south Mumbai will be lit up in the colours of the national flag as part of the 'Har Ghar Tiranga' campaign for the next three days, a civic official said on Friday.

The Brihanmumbai Municipal Corporation (BMC) will spend Rs 48 lakh to illuminate 28 art deco buildings lining the Queen's Necklace stretch from August 13 to 15, he said.
