A few prosaic facts, gleaned from the All-knowing Internet, just to establish its historical roots. 1) Built by the Kutchi-Memon community (originally from Gujarat). Mariners or Seafarers, they are also called Nakhoda. 2) Work started in 1926 and was completed in 1934/5. Abdul Rahim Osman donated the largest amount. Total cost was 1,500,000 INR. 3) 10,000 can offer prayers at any one time. The architecture is mind-blowing. Reminiscent of what I recall seeing at Agra and Sikandra. However, since women are not allowed in, my review will only extend to what can be seen from the streets. Please bear in mind that this is an active place of worship and not a tourist spot per se. Taking permission to enter (if allowed), and take photographs, is a good idea, especially if prayers are being offered at that time. The doorway is MAGNIFICENT. The clocks show the prayer timings. The domes bring Taj-Mahal to mind. The place is extremely well maintained. The road outside is CHAOTIC. It overwhelms the senses. The variety of things being sold boggles the mind. People are polite and helpful especially about directing you to 100 and 105 year old eateries that lie withing a stone's throw. Traffic is uni-directional (One-way as we put it) l Traffic violations can be expensive; rates have been revised. Parking is IMPOSSIBLE. I wish I could have entered and seen the beautiful inlays myself but since that is not possible, I have consoled myself with having seen just the exterior. That, even just by itself is a visual treat.
