The Defence Colony Flyover Flea Market operates under the flyover on Lala Lajpat Rai Marg, a rambling weekend market selling antiques, collectibles, vintage posters, old books, brassware, and curios. It is one of Delhi's best-kept secrets for treasure hunting — the kind of flea market where genuine finds can be made alongside the usual tourist bric-a-brac. Regular visitors know to arrive early and look through everything.
The market operates on Saturday and Sunday mornings, starting around 8am and winding down by midday. Prices are negotiable and the range of goods covers everything from 19th-century company paintings to colonial-era furniture. The neighbourhood's proximity to the diplomatic enclave means diplomatic families often sell household goods here when they depart, occasionally yielding unusual finds.
