Ahsan Manzil situated at Kumartoli of Dhaka on the bank of the Buriganga, was the residential palace and the kachari of the Nawabs of Dhaka. It has been turned into a museum recently.
The construction of the palace was begun in 1859 and completed in 1872. Abdul Ghani named it Ahsan Manzil after his son Khwaja Ahsanullah. At that time the newly built palace was known as Rang Mahal and the earlier one was called Andar Mahal.
Ahsan Manzil is one of the significant architectural monuments of the country. Established on a raised platform of 1 metre, the two-storied palace measures 125.4m by 28.75m. The height of the ground floor is 5 metres and that of the first floor 5.8 metres.
