Next walk down or take an auto to the Hooghly Imambara (built in 1861) whose elegant minarets are visible from afar. Buy a pass for INR 20-30 to experience the grandeur from ancient clocks to Islamic calligraphy on the walls, the peaceful aura of the Imambara will transform you into a different age.

But it is most well known for its vaunted clock bought in 1852 from M/s Black & Hurray Co., Big Ben, London. It’s located between 15-ft high twin towers on the epic doorway and has two dials with three bells – the smaller ones ring at an interval of 15 minutes and the bigger ones every hour. The clock requires two people to wind it for half an hour of each week with a key weighing 20 kg!
