In 1917, the Mohammedan and Hindu Endowments Board took over the management of the mosque until 1968, when it handed the reins over to Majlis Ugama Islam Singapura (MUIS).

[1] Worshippers enter the mosque through a gateway framed by two minarets topped by onion domes and a miniature four-storey palace façade.

Rising out of solid bases, each minaret comprises seven levels embellished with a miniature mihrab motif and deep recesses.

It also contains a shrine to an early local Muslim religious leader, Muhammad Salih Waliullah, whose grave existed on the site before the construction of the mosque in the 1830s.

Beyond the foyer is the ancillary prayer hall, a square airy room with arched openings in its brick walls.

While the entrance gate is distinctively South Indian, the two prayer halls and the shrine are in the Neo-Classical style typical of George Drumgoole Coleman, the first trained architect in Singapore.
