Ahsan monjil.

Ahsan Manzil is one of the most significant architectural monuments of Bangladesh. Established on a raised platform of 1 metre, the two-storied palace measures 125.4 m by 28.75 m. The height of the ground floor is 5 metres and that of the first floor 5.8 metres. There are porticos the height of the ground floor, both on the northern and southern sides of the palace. An open spacious stairway comes down from the southern portico, extending onto the bank of the river through the front garden. There was once a fountain in the garden in front of the stairs, that does not exist today. The spacious north and south verandas of both the floors rest on semicircular arches. The verandas and rooms are covered with marble.

To construct the dome of Ahsan Manzil, the square room on the ground floor was given a round shape with brickwork in the corners. The room was then given an octagonal shape near the roof by squinches. This octagonal shape took the form of the drum of the dome. Finally, the kumud kali (buds of lotus) shaped dome was constructed by gradually slanting the eight corners to the peak. The dome is 27.13 m above the ground.

the national mosque of bangladesh.

It is the National Mosque of Bangladesh. Its construction began on 1960, and has been going on in phases. Architect T Abdul Hussain Thariani was commissioned to design the mosque complex. The plan included shops, offices, libraries and parking areas within the complex. The design of the mosque reflects the architecture of the period as can be seen from the use of a white and almost cube-form for the main building. A Mosque without a dome over the roof of its main prayer hall must have been a unique experiment. The main building is eight storied and 33 meters high from the ground level. The area of the main prayer hall is 2464 SQ meters with a mezzanine floor of 171 SQ metres at the eastern side. Verandas surround the hall on three of its four sides. The mihrab of the hall is rectangular instead of semi-circular. Excessive ornamentation is avoided throughout the mosque, since minimizing ornamentation is typical of modern architecture. The Baitul Mukarram mosque is modern in its architectural style. It has found its place in the hearts of the Muslims because of the resemblance of its form to the Holy Kaaba at Makkah.
