Pause at the Baghdad Street end of pedestrianized Bussorah Street for a good view of the golden onion domes of the Sultan Mosque or Masjid Sultan, the beating heart of the Muslim faith in Singapore. An earlier mosque stood on this site, finished in 1825 and constructed with the help of a $3000 donation from the East India Company. The present building was completed a century later to a design by colonial architects Swan and MacLaren. Look carefully at the base of the main dome and you’ll see a dark band that looks like tilework, though it actually consists of the bottoms of thousands of glass bottles. The wide foyer has a digital display listing prayer times. Beyond and out of bounds to non-Muslims is the main prayer hall, a large, bare chamber fronted by two more digital clocks.
