A couple of kilometres from the church is the Hooghly Imambara, a congregational hall for the Shia sect, especially for observing Muharram. Although the complex looks somewhat run down, the architecture is bound to impress at first sight. The two storied building, with arched corridors running along the sides, is built around an open air rectangular courtyard. In the centre of the courtyard is a water tank and a few fountains, which had definitely seen better days. Two towers, each over 85 feet high, rise on either side of the entrance and are connected with each other via the clock tower. With permission, it is possible to reach the top of these towers (separate entrance for men and women). The prayer hall, with walls decorated with Islamic inscriptions, contains some old chandeliers and lamps. Built with donations from Bengali philanthropist Haji Mohammad Mohsin, the Imambara was completed between 1841 and 1861. There is a nominal entry fee. It remains open between 8 am and 5 pm daily except during religious functions.
