Ahsan Manzil is the erstwhile official residential palace and seat of the Nawab of Dhaka. The building is situated at Kumartoli along the banks of the Buriganga River in Dhaka, Bangladesh. Construction was started in 1859 and was completed in 1872. It was constructed in the Indo-Saracenic Revival architecture. It has been designated as a national museum.
In Mughal era, there was a garden house of Sheikh Enayet Ullah, the landlord of Jamalpur Porgona (district), in this place. Sheikh Enayet Ullah was a very charming person, who acquired a very big area in Kumartoli (Kumartuli) and included it in his garden house. Here he built a beautiful palace and named it "Rongmohol" (Rangmahal). He used to enjoy here keeping beautiful girls collected from the country and abroad, dressing them with gorgeous dresses and expensive ornaments. There is a saying that, the founder of Dhaka (representative of mughal emperor) was attracted to one of the girls. He invited Sheikh Enayet Ullah to a party one night and killed him in a conspiracy when he was returning home. In anger and sorrow, the girl committed suicide. There was a grave of Sheikh Enayet Ullah in the north-east corner of the palace yard which was ruined in the beginning of the 20th century.
Probably in the period of Nawab Alibardi Khan(Grandfather of Nawab Siraj-Ud-Daulah) around 1740 century, Sheikh Moti Ullah, the son of Sheikh Enayet Ullah, sold the property to the French traders. There was a French trading house beside this property. The trading house became wealthier after purchasing this property. In that time, French traders could do business here without paying any taxes by a decree from the emperor Aurangzeb. In that time, the French became very wealthy by doing business here in competition with the English and other European companies. They made a big palace and dug a pond for sweet water in the newly purchased property. The pond still exists in the compound of Ahsan Manzil which was called "Les Jalla" in that time. In the Seven Years' War, the French got defeated and all their properties were captured by the English. On 22 June 1757, the French left the trading house with a fleet of 35 boats from the river station of Buriganga in front of Kumartuli.
In 1785, the French transferred the property to a French tradesman named Mr. Champigni, and retaken it at 1801. According to Paris agreement of 1814, the French claimed all their left properties at Dhaka, and in 1827 the property was again returned to the French. For the increasing power of the English, the French was forced to leave subcontinent. They decided to sell all their properties in Dhaka. So in 1830, the trading house of Kumartuli was purchased by the established landlord of Dhaka, Khwaja Alimullah.
After some renovation work, the trading house became the residence of Khwaja Alimullah. In his time, a stable and a family mosque was added in the compound. After his death, his son Nawab Bahadur Sir Khwaja Abdul Ghani made a great flourish to the property, and named it "Ahsan Manzil" after his son Khwaja Ahsanullah. In the east side of the old building, he made a new building with a different design, and also done great renovation work to the old building. Since then, the old building was called "Ondor Mohol" and the new building was called "Rangmahal".
In the evening of 7 April 1888, a devastating tornado hit Dhaka city causing great damage. Ahsan Manzil was severely damaged and abandoned. An English engineer from Kolkata arrived here to examine the palace. He gave an opinion that except for the "Rangmahal", all the other parts of the palace would have to be reconstructed. So Nawab Bahadur Sir Khwaja Abdul Ghani and his son Nawab Bahadur Sir Khwaja Ahsanullah turned their full attention to rebuild the palace. Both of the buildings were reconstructed during that time with a new design and supervised by the local engineer Gobinda Chandra Roy.
The old French building was reconstructed to a two storied building keeping similarity to the Rangmahal. A gangway was made with wood connecting the first floors of the two buildings. The most beautiful thing made in this time was the dome, which enhanced the beauty of the palace.
After the death of Khwaja Ahsanullah in 1901, the glory of Ahsan Manzil was ended. His successors could not continue the glory because of the internal family quarrel. They rented different parts of the palace to tenants, who actually made it a slum. In 1952, government acquired the property and left in supervision of the Dhaka Nawab court. In 1985, Dhaka National Museum acquired the property and made it a museum following a massive restoration programme which utilised historic photographs of the property.
Ahsan Manzil is one of the most significant architectural monuments of Bangladesh. The building structure was established on a raised platform of 1 meter, the two-storied palace measures 125.4m by 28.75m. The height of the ground floor is 5 meters and the height of the first floor is 5.8 meters. The thickness of the walls of the palace is about 0.78 meters. There are porticos of 5 meters height on the northern and southern sides of the palace. The building has a broad front-facing the Buriganga River. On the river side, an open spacious stairway leads right up to the second portal and on their stands the grand triple- arched portals. There was once a fountain in the garden in front of the stairs which does not exist today. All along the north and the south side of the building run spacious verandahs with an open terrace projected in the middle.
The palace Ahsan Manzil is divided into two parts: the eastern side and the western side. The eastern building with the dome is called the Rangmahal and the western side with the living rooms is called Andarmahal. The high octagonal dome is placed on the central round room. There is a large drawing room, card room, library, state room and two other guest rooms are located on the east side of the palace. The ballroom, the Hindustani room and few residential rooms are situated on the western side. A beautiful vaulted artificial ceiling, made of wood, decorates the drawing room and the Jalsaghar. A splendid dining hall and few smaller rooms are placed on the west part. The floors of the dining and Darbar Halls are decorated with white, green and yellow colored ceramic tiles. The famous store room, where the valuables of the Nawabs used to be stored, was in the middle of the five rooms located in the western half of the ground floor. Along with those rooms a Darbar Hall or assembly hall and a chest room is also place there.
There are attractive wooden stairs in the room that is attached to the north of the domed room. The balusters were ornamented with vine leaves made of iron along the railing of the stairs. The wooden ceiling of the room, decorated with geometric designs, is very elegant. The verandas and rooms are covered with marble. The doorways are placed within semicircular arches. The inner doors had multi-colored glasses. Wooden beams supported the roof of these rooms. The architecture and the decoration is one of a kind in whole Bangladesh.
The construction of the famous dome of the Ahsan Manzil, which is at the center of the palace, took tedious planning. The square room on the ground floor was built with a round shape and brickworks were done around the corners. To give the room an octagonal shape, squinches were given around the roof corners. The eight corners of the octagon was slanted gradually to make the dome look like the bud of a lotus (Kumud Kali). The peak of this dome is 27.13 m above the ground. Ahsan Manzil was severely damaged during the tornado that occurred on 7 April 1888.the western block of Andermahal was completely demolished and later it was entirely rebuilt. The present day dome, which is situated on the top, was built during the time of reconstruction. This place was also damaged during the earthquake of 1897 but Nawab Khwaja Ahsanullah repaired the whole place again.
In 1874, Lord Northbrook, Governor General of India attended an evening function in the palace when he came to lay the foundation of a water works installed by Nawab Abdul Ghani. In 1888, Lord Dufferin also accepted the hospitality offered at Ahsan Manzil. In 1904 Lord Curzon, on a visit to East Bengal, stayed in this palace on 18 and 19 February to win public support for the proposed Partition of Bengal.
Ahsan Manzil, an architectural treasure, is a witness to many historical events of Bangladesh. From the last part of the 19th century to the initial years of Pakistan, the Muslim leadership of East Bengal emerged from this palace. The nawabs of Dhaka used to conduct their court affairs here as chief of the Panchayet (village council) every day. Many anti-Congress meetings were held here under the patronization of Nawab Ahsanullah, a staunch believer in Muslim identity. Almost all the Viceroys, Governors and Lieutenant Governors of British India who visited Dhaka spent some time at the Ahsan Manzil. Almost all political activities of Nawab Khwaja Salimullah centred round this palace. Ahsan Manzil was the cradle of the All India Muslim League. With the decline of the Nawabs of Dhaka, Ahsan Manzil also started to decline.
In 1952, the Dhaka Nawab State was acquired under the East Bengal Estate Acquisition Act; it became impossible for the successors of the Nawabs to maintain the palace due to financial constraints. Nawab Khwaja Habibullah started living at Paribag Green House soon after the acquisition of the zamindari. The palace was soon on the verge of collapse as successors rented out rooms without considering its dignity. Over the years illegal occupants turned the place into a filthy slum. After the independence of Bangladesh, most of the nawab family went to abroad in search of a better livelihood and work. On 1974, the owners of the palace decided to put it up for auction.
Recognizing the historical and architectural importance of the Ahsan Manzil, the government of Bangladesh took the initiative to renovate it. In 1985, Ahsan Manzil and its surroundings were acquired. After the completion of the renovation work in 1992 under the supervision of the Directorate of Public Works and Architecture, it was brought under the control of Bangladesh National Museum (20 September 1992). A museum has been established there.
After the implementation of the work on the museum started, most of the nawab's house area along with the half of the portion of the Andarmahal remained beyond acquisition. The total area of acquired land was 5.65 acres. Out of that 0.68 acres from northern side was given to Dhaka City Corporation to establish a super market and 4.96 acres of land with the palace buildings remained for museum purpose. In 1986, the work began according to the above order keeping the original structure undisturbed and reconstructing the old environment as far as possible. After the completion of the renovation work in 1992, under the supervision of the Directorate of Public Works and Architecture, it was brought under the control of Bangladesh National Museum (20 September 1992). A museum has been established there.
