The Bada Imambara(Big) lies in the old city. It was built by the Nawab of Awadh, Asif-ud-Daula in 1784. The complex consists of several buildings. It has a mosque, a labyrinth and a bowli- a step well. The labyrinth, commonly called a maze is one of the main attractions here, it might get a bit confusing to find your way out here with lots of steps, yet people have a great time solving that puzzle. It might become a little difficult if you forget to carry a torch. The Bada Imambara is a great place to see cultural integration in terms of architecture, a Nawab's care for the people of his kingdom and the techniques adopted to ensure maximum security. There is a combined entry fee of Rs. 50 for Indian citizens and with a slight variation for other citizens. There are guides available at a fixed cost. Just outside the Imambara there are small shops where there are goods sold which are made out of camel bone.
From the Bada Imambara , it's easy to get a shared rickshaw for Rs. 10 per person to the Chota Imambara(Small). On the way do not forget to stop at the clock tower and the picture gallery which has paintings of the Nawabs who ruled the city.
