I got a very good idea from reading the details of your travel experience at Baitul Mukarram National Mosque. I visited it once, but due to a lack of time, I could not see everything properly. Despite being located between Paltan and Gulistan, two of Dhaka's busiest areas, the calm and serene atmosphere inside is truly admirable. The description you have given in the post of the square architecture of the mosque, modelled after the Kaaba Sharif, is particularly eye-catching. Especially, despite the lack of a dome, the use of calligraphy and geometric designs on the inner walls and the modern roof plan to let in daylight are great. I think it is quite challenging to maintain such a large and orderly religious establishment right in the heart of a busy commercial area, which is being managed quite well by the Islamic Foundation Bangladesh. I think it will work as a complete guide for any new visitor, as it mentions civic amenities like the library and ablution facilities inside the mosque. Best wishes to you in this contest. 😊
