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 of171 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.
