Delhi is a hard city to love because it is too big to know. We all like bits of it; my favourite parts are the Kashmiri Gate/ Civil Lines/University area in Old Delhi and the Lodi Gardens/Khan Market/India Gate zone in Lutyens' Delhi. I grew up in these places and they fill me with the comfort of recognition. That said, I can't tell you when the Exchange in Civil Lines was built or name the mosque at the end of Pandara Road, the one that houses a nursery. I can't look up these facts because the city's urban fabric-its monuments, localities, parks, public buildings, domestic architecture-is virtually undocumented. A nostalgia without names diminishes memory because there can be no intimacy without information and anonymous cities breed strangers.
