Complaining about multiple civic agencies’ failure to keep a portion of the Mehrauli Archaeological Park clean, some residents of Ward 7 in Mehrauli sat on a dharna outside their apartment complex on Sunday.

A part of the park -- which boasts monuments like the ruins of the tomb of the 13th Century Delhi ruler Ghiyasuddin Balban, the 16th Century Jamali-Kamali mosque, the 19th Century Metcalfe’s canopy and the ruins of several other Lodhi-Mughal era structures -- has manicured lawns and footpaths where “heritage walks” have become popular with tourists.
