Amid the prosperous neighbourhoods of south Delhi are scattered vestiges of several former capitals, spanning over 3,000 years of Indian history. Most conspicuous among them are the tombs of the country’s first Islamic rulers, which range from the magnificent, red-and-white mausoleum of Mughal Emperor Humayun to the splendour of the Lodi Garden. Most jaw-dropping of all is the Q’tub Minar, a giant, tapering pillar of victory dating from 1182AD. A perfect pitstop on your tour is the 13th-century Hauz Khas complex, home to a bumper crop of trendy boutiques, art galleries and antique emporia.
