Though more than 80 mosques exist on the island of Singapore, Sultan Mosque is the real center of the Muslim community. The mosque that stands today is the second Sultan Mosque to be built on this site. The first was built in 1826, partially funded by the East India Company as part of their agreement to leave Kampong Glam to Sultan Hussein and his family in return for sovereign rights to Singapore. The present mosque was built in 1928 and was funded by donations from the Muslim community. The Saracenic flavor of the onion domes, topped with crescent moons and stars, is complemented by Mogul cupolas. Funny thing, though: The mosque was designed by an Irish guy named Denis Santry, who was working for the architectural firm Swan and McLaren.

Other interesting facts about the mosque: Its dome base is a ring of black bottles; the carpeting was donated by a prince of Saudi Arabia and bears his emblem; and at the back of the compound, North Bridge Road has a kink in it, showing where the mosque invaded the nicely planned urban grid pattern. Also, if you make your way through the chink where the back of the building almost touches the compound wall, peer inside the makam to see the royal graves. Sultan Mosque, like all the others, does not permit shorts, miniskirts, low necklines, or other revealing clothing to be worn inside. However, they do realize that non-Muslim travelers like to be comfortable as they tour around and provide cloaks free of charge. They hang just to the right as you walk up the stairs.
