If there's one place that sets Lucknow apart, it is the nawabi heritage of old Lucknow. Build over a century ago and more, unique houses in the area stand to this day. The elegant architecture in these houses, including delicate 'jaali' work with a Persian touch, is only one of the enthralling aspects in these structures.

Often, the construction process and the building material used also shocks visitors. Just like the Imambara, houses here too have been built using things like urad dal, tree gum, and jaggery.
